Problem:
I'm trying to install LAMP Stack using following article. However, I was getting HTTP 500 Error while accessing phpmyadmin from browser.
And installed phpmyadmin using below command.
sudo apt install phpmyadmin php-mbstring php-zip php-gd php-json php-curl
Tried:
So, I checked with Error Log tail -f /var/log/apache2/error.log and found that Phpmyadmin was running on depreciated version of PHP.

If you have installed php mysql and apache directly on your system. Uninstall them and install only lamp. By so doing there will be no conflict and you stop having internal server error due too deprecated php version.
I am having trouble with apache2 error.log. The 500 errors are not appearing there (/var/log/apache2/error.log), I am just getting these lines every time I restart the apache2 service :

I put error_reporting = E_ALL, display_errors = On, display_startup_errors = On, log_errors = On in the /etc/php/7.4/apache2/php.ini AND /etc/php/7.4/cli/php.ini.
I don't even get the errors on the browser, I am just receiving a message in the inspector "500 Internal Servor Error".
What else should I configure to make them appear in the error.log?
Ok, I missed one thing, such the biggest thing.
I had to change the LogLevel from warn to debug in apache2.conf file (/etc/apache2/apache2.conf) and now it works !
I am having a strange error (system is Ubuntu 16.04):

PHP version is 7.1.19. I installed curl (apt-get install php7.1-curl), in the php.ini I added extension=curl.co (and commented out extension=php_curl.dll), restarted the apache service, and the error is still there (I tried commenting out extension=curl.co but the error is still there).
This is an error I am getting on the page (Laravel setup):
Call to undefined function App\curl_init()
Everything is installed and config files are as required and I don't know what could be wrong here.
The /etc/php/7.1/mods-available/curl.ini file content should be:
extension=curl.so
Please notice the extension is .so, and not .co.
Then you can enable the module in your PHP by running:
$ sudo phpenmod curl
Finally, you may need to restart your Apache:
$ sudo systemctl restart apache2
I have installed the latest Nextcloud container on my Ubuntu machine.
It started successfully with the following command:
sudo docker run --name nextcloud --link mysql:mysql -p 9000:9000 -v /data/nextcloud:/var/www/html -d nextcloud:latest
The comand sudo docker logs nextcloud shows:

I enabled mod_proxy and mod_proxy_fcgi on the Apache configuration of the host machine, so this is not running inside another docker container.

What have I missed?
I think that using nextcloud:latest, you are getting the image using Apache, not the one using fpm.
Try to use nextcloud:fpm with your proxy setup, or using the default image without proxy (ie accessing it directly).
I can't get APC to work on Windows because Apache keeps crashing as soon as I run a php file. Is this issue know and is there a workaround?
Versions:
Apache 2.2.14
PHP 3.1
APC 3.1.3
The best route to solve this type of problem is to check your Apache log files and see what issues were raised. An example of these logs follows:
[Wed Jun 03 06:07:47 2009] [alert] [client 127.0.0.1] C:/wamp/www/WebsiteA/.htaccess: Invalid command 'RewriteEngine', perhaps misspelled or defined by a module not included in the server configuration
