Question Media upload only small images

I use the server with Wordpress and I have problems uploading media. I can only upload very small images. I tried to change the PHP settings, but all settings seemed ok to me.

PHP version 7.4

The error is The server is too bussy or the file are too big.

Please help me out.

I will try. When I use nginx I have no problem.

I tried post_max_size 120M, but still the message:

Image post-processing failed because the server was busy or does not have enough resources. Uploading a smaller image can help. Recommended maximum size is 2500 pixels.

I did some checks and when I install WordPress and change permalinks in WordPress to filename I get an access error..

That is becouse in ultra webserver in apache http.conf file the 'Options Indexes FollowSymLinks' is comented out. The default setting in other webservers (xampp) is:

'Options Indexes FollowSymLinks Includes ExecCGI'

When I change it in the http.conf in ultra webserver all works.
