I am hosting a site locally via MAMP, but somehow while editing sidebar (tried to edit widgets), site went blank and it cannot give me access to wordpress admin panel. It shows up 500 error and blank page.
Site has multiple themes assigned to different pages, so when I try to access homepage (arcade basic theme) it works fine. But when I try to access Shop (mystile theme), it shows blank page and 500 error.
The 500 error is also received when I try to access admin panel via wordpress dashboard (on my homepage).
what can I do?
Just in case you didn't know, 500 errors mean there's a server misconfiguration somewhere.
This could easily be down to an error in coding, which clearly this sounds like.
You would be helped greatly by looking in your apache error logs (usually in your log folders), this should tell you what caused the error - or you could also try turning PHP error display on, which may display the same information but on the screen.
Once you find out where abouts in the code the error is being generated, update your answer, along with an excerpt of that area of the code, and others may be able to help you better.
Another suggestion would be to try using an IDE software application to write your code, as this will flag up any errors as you type them. Personally, I use NetBeans.

I have a WordPress plugin that when activated on a production server causes the pages (only on front-end, not on the wp-admin side) to show up as a blank screen and sometimes print a 503 error. The console shows no error output and neither does the source show much of anything (besides the 503 error). I don't see anything in the debug log either.
On localhost with wampserver - everything works fine.
What could possibly be going wrong and how do I resolve this?
I am a bit lost at this point since there isn't an error pointing me to where the issue is. Just a blank screen when you activate the plugin.
This is not necessarily a fix in terms of figuring out what was wrong - but updating other plugins seemed to resolve some plugin conflict and the plugin is now working.
I have wordpress multisite set up on Server 2012/IIS 8 using subdirectories rather than subdomains for each site.
I have set up 6 sites but 4 of them give 404 when I attempt to bring up the dashboard (/wp-admin/) or visit the site
I thought maybe some of the sites had somehow gotten corrupted so I created a new site but it gives a 404 as well.
I cannot see any obvious difference between the sites that work and those that don't.
The only clue I have is that the 404 requests don't even show up in the IIS log.
I have discovered what is going wrong but not why. The sites run on an internal url http:localhost:8100. On the newly created site when I go to edit page it was showing http://localhost/. This is why it was not showing up in the IIS logs.
Unfortunately, If I try to change it, it just reverts. The working sites all show http://localhost:8100/ If I change siteurl and home under settings for the non-working site they also just revert back. So I've discovered the 404 problem but don't yet have a solution
I'm having some trouble with a drupal page. The website is loading and nothing is out of the ordinarty. But when you load the page with Google Chrome development shizzle (when you press F12) and put it on Network and then reload the page, you see that the first thing that happens is receive an 404 error.
It's not that big of a deal but our monitoring system says the website is offline because of this.
Does anyone knows what is going on? I have absolutely no idea why this is happening.
I'm running into this exact problem with a D7 site on a new server that has PHP 5.5.9 installed - the page loads but the HTTP header says "HTTP/1.1 404 Not Found" for all pages but the homepage. If I work out a solution I'll post it here.
Update: It turned out my problem was that mod_rewrite was not enabled, once I enabled it the site started working correctly.
Drupal allows customizing 404-403 error pages. Probably, your site (by some reason) displays content on 403/404 pages.
At first, clear cache (using web ui or drush).
This can be 1-page issue (check /user/login, admin pages, node pages). Maybe, only your front page is not found.
If this is not 1-page issue, check and disable customerror module (if you has one installed).
For 2 days now I have been trying to access my admin page for the zencart on a site I am working on, I have re-uploaded the whole zencart numerous times and I keep getting a blank page when I go to the admin section. Can anyone help?
We will probably need more details to really be able to help. If you just see a blank page (have you checked the source code in the browser? Is it completely blank?) you will need to check the error logs to be able to trace the problem.
If you are using Zen Cart version 1.3.8a or higher you will have the error logging tool enabled by default, so you can have a look for logging files inside the /catalog/cache folder. Take a look at a few files and look for fatal errors, because you probably will have one of those if you are getting a blank page.
By the way, that kind of error doesn't happen without good reason, What is the last thing you have modified/added to your admin site? A new contribution perhaps?
I am running a site on php with a mysql backend. Things have been fine but suddenly one users account started getting a 500 error. Each user has his own profile when they log into the any box so his internet explorer settings are the same no matter what box he logs on to. Does anyone know if this could be an internet explorer setting causing this? I have tried to debug everything on the client side and no matter what I do he is getting rejected. No other account is having this issue. I am not really an SA but the only thing I think it can be at this point is some setting within his profile which is causing this. This is also happening on firefox but instead of a 500 error I am getting a blank white screen. (I assume friendly error messages are turned on)
The issue had to do with a permission not properly set in one of the log folders. The system was trying to write to the log folder and for some reason that particular user was not set to have write access. The problem was impossible to track down but thanks for the help.
If this is programming related, it might help turning error displaying on in php, using error reporting:
<? error_reporting(E_ALL); ?>
Could be the browser acting up, sending weird headers or mangling requests because of addons or malware.
