When uploading a 50MB file in WordPress through any of the methods it provides, I experienced an error message saying
HTTP error.
with no further hint what has happened. I tried uploading other types of similar size and different file types of smaller size. Only files above a certain size failed no matter what type and all types of smaller size succeeded.
I raised maximum file and post size in php.ini (upload_max_filesize, post_max_size) and the network settings of WP up to four times the size of the file but to no avail.
I found out that the error was 404 even though the file which 404ed was physically there. Upon further inspection of the answer I found out that IIS answered with a more detailed error code of "404.13" which further hints to the request filtering module and the solution (below)
This problem is related to the file's size but has nothing to do with WordPress or PHP or the filesystem but with settings in IIS.
In IIS there is a feature called "Request Filtering" where you can set filtering rules for requests based on various things like HTTP verbs, file extensions, and so on. Unfortunately the UI of IIS often is not very clear and hides important links in the side bar on the right side which puts things out of attention on wide monitors.
Solution
Open "Request Filtering"
Click on "Edit Feature Settings..." in the sidebar
change the value of "Maximum allowed content length (Bytes)"

This is not a quick failure, I have spent a totally of 5 completely full days trying to figure this out. Initially I was limited by file size and then file type; in which I removed the Wordpress restrictions and am now "capable" of uploading my 177MB .glb file to Wordpress.
However when doing so, I receive the following error:
retriever.glb
Unexpected response from the server. The file may have been uploaded successfully. Check in the Media Library or reload the page.
I was on the phone with GoDaddy Specialists for 2.5 hours yesterday ensuring that this was not a Server issue or restriction on their side.. they confirmed that it was not. We pretty much ended the conversation that it is something I must figure out with me, myself, and I.
I went ahead and uploaded my .glb to the server through panel, everything worked fine. In fact I have a location for it here: https://www.tattiniboots.com/wp-content/uploads/2020/07/retriever.glb
However, this does not make the file discoverable to the 3D viewer plugins I have installed on the site through the media location.
I truly don't know where to go from here
I changed the name of the file to .png and attempted an upload and received the following error:
Post-processing of the image failed likely because the server is busy or does not have enough resources. Uploading a smaller image may help. Suggested maximum size is 2500 pixels.
I just tried to update a normal .mov file that is 150MB and received the following error; really making me think this is something to do with file size:
Unexpected response from the server. The file may have been uploaded successfully. Check in the Media Library or reload the page.
Yes, normal images are uploading just fine (2MB-ish)
I just attempted to deactivate all plugins with consideration that maybe "Smush" or another was imposing issues: I then received the issue that the file type is not supported (even with the allow all file types code in my wp-config)
Is this just the case that glb is not allowed at all?
This must be a server thing. probably a run time error
Whoever supported you just doesn't know it. GoGoDaddy. ;)
Nevertheless... you can Use a plugin that's called
media sync. Check it out and best of luck
I am using the script posted here by w3school for uploading files to a webserver. I am using Google chrome going to an Apache server with php7.
When I upload a file from my windows desktop the script works as advertised and the file is uploaded. However when I attempt to upload a file from any other folder the $_FILES variable is either not there or it's values are empty (It actually appears to be a size issue, see edit below). I'm not sure how to troubleshoot this as the devtools on chrome don't seem to give me any information about what it is sending in this POST message.
I am assuming the problem is on the client side as it appears the server is getting no information from the client.
EDIT
I am aware of how to look at the headers for requests and nothing about the file except for its content length are included in the header. There is no difference between the headers that work and those that don't except the content boundary, which appears to be random, and the content-length header, which obviously changes with the size of the file.
I had a thought that this was related to the size of the file, and it is. I have a folder of different size photos and I sorted and uploaded increasingly larger files until it failed. It worked fine until around 8M files, and fails when they are larger than 8,200KB.
I checked the php.ini and I have it set to a max upload size of 150M, so it's not the ini file. I also check all the logs and nothing other than the post request shows up when I try to upload the file.
I was able to find the answer here: why would $_FILES be empty when uploading files to PHP.
I did not know there was a post_max_size option in the php.ini file, which was set to 8M. Now that this is set to 100M. If you go over this size of a POST request php does not parse the POST information, thus giving you a blank $_FILES variable.
I have a problem when attempting to upload really big files using PHP. I know this has been raised before and I have read many responses, but I have not found a definitive answer.
The basic code I use is posted here: http://design.wildsandwebdesign.co.uk/technical/uploading-files-2.php and I have used this with complete success for letting client upload image files, JPEG, GIF, png etc. The problem arose in allowing users to upload non-displayable files such as .psd files which can be very large.
In php.ini on both my local and remote servers upload_max_filesize and post_max_size are set to 128MB. The hidden field MAX_FILE_SIZE in the code has been set to various values during development. The problem is this: If the user selects a file bigger than the MAX_FILE_SIZE but smaller than 128MB,$_FILES['uploadfile']['error'] returns an error code of 2 as the PHP documentation says it will. If the file size exceeds 128MB then the upload handling fails altogether with bizarre results.
The “bizarre” results include irrelevant error messages such as “Undefined index: uploadbtn” this being the index of the submit button you have to click to get the error message(!) This happens with Firefox 26 and with Chrome. Bigger files can crash Firefox altogether which then displays the bug report dialog.
I don't want to upload files larger than 128MB, I just want to handle the situation where a user selects a very large file in some reasonable way. Does anyone know how to do this?
The production code is very much more complicated than the example above but I will happily provide it on request.

I am currently working on a simple php website
The problem is , the images in my whole web site(happens in all php files) randomly corrupt and show the error
Resource interpreted as Image but transferred with MIME type text/html, however, if I try to refresh the page several times. The image can be loaded again and the error is gone.
I have checked all img path and the image is exist. Also, I checked there is no img src="" in my file. Is it due to server setting? I check .htaccess file and it is blank. How to fix the problem ? Thanks
One possible reason for this could be an intermittent server error, which serves an error page instead of the image resource.
Apache's access.log will tell you which response code the images were sent with (200 means "ok"). error.log will tell you the exact error message if you find an error.
This could also be the intermittent hick-up of a company or ISP proxy server.
I'm offering users the ability to upload files using an online form, but I keep on getting 500 internal server errors whenever the file upload is processed. This is what I know:
The problem isn't related to php.ini. I've checked the max file upload size, and it's set at 2 megabytes. I get the same 500 internal server error uploading 3kb large files, as well as 100kb large files.
The problem isn't related to file permissions. The php file I'm using to upload, upload.php, has permissions set to 664, and the upload folder, called upload_pic, has folder permissions of 755.
This is not an issue with the code. The exact same code was working on my previous server. I recently bought a new server and am migrating the sites over, and this is where I'm getting my problem.
I've looked online for the past two days, but I just can't find what's causing the problem. I've seen many issues similar to mine, but most of these were resolved by changing file/directory permissions, or making edits to php.ini.
Does anyone have any other proposed solutions?
Thanks!
