Cannot upload an avatar

[Creature Bipedal]

After I tried to upload an avatar, the forum stopped responding completely. All pages fail to load and the browser showed ERR_CONNECTION_TIMED_OUT.

This looks like the PHP process handling the avatar upload got stuck or crashed, causing the web server to stop responding.

Likely causes:

• insufficient PHP memory_limit during image processing;
• GD/ImageMagick hanging while resizing the image;
• write permission issues in images/avatars/upload/;
• PHP execution time being exceeded.

Please check the PHP and web server error logs and restart Apache/Nginx.

The forum was completely unavailable.
