Hey there, let's tackle your issue head-on—first, we'll separate the unrelated warning from the actual upload timeout problem, then walk through actionable fixes.

First: Understanding the Debug Log Warning #

The line in your debug.log:

May 13 21:15:36 +0000 OX-5af8aaf8338bc [ warning] Declaration of HTML_QuickForm_file::_findValue() should be compatible with HTML_QuickForm_element::_findValue(&$values)

This is a PHP compatibility warning, not the root cause of your upload timeout. Here's what it means:

• The HTML_QuickForm_file class has a method _findValue() whose signature doesn't match its parent class HTML_QuickForm_element. Specifically, the parent method expects a referenced parameter (&$values), but the child method doesn't use the same syntax.
• This usually happens when you're running a newer PHP version (7.x+) with older, unupdated code from the HTML_QuickForm library. While it's a sign the code needs maintenance, it won't block file uploads or cause connection timeouts. You can ignore this warning for now while fixing the upload issue.

Fixing the "Connection Timeout" Upload Issue #

Since changing file permissions to 0777 didn't help, let's dig into the more likely culprits:

1. Verify PHP Upload Configuration #

Check your server's php.ini file for these critical settings (adjust values as needed for your image sizes):

• upload_max_filesize: Should be larger than your image file size (e.g., 10M for 10MB images)
• post_max_size: Must be bigger than upload_max_filesize (e.g., 12M)
• max_execution_time: Increase this if uploads take longer than the default (e.g., 60 for 60 seconds)
• max_input_time: Same as above—set to a value that allows enough time for the upload to complete

After modifying php.ini, restart your web server (Apache/Nginx) for changes to take effect.

2. Check Network & Firewall Restrictions #

• Outbound Connections: Ensure your server isn't blocked from connecting to the Ad Revive server. Check your server's firewall rules, security groups, or any web application firewall (WAF) that might be blocking requests to the Ad Revive upload endpoint.
• Test Direct Connection: Use curl from your server to test if you can reach the Ad Revive upload service. For example:

  curl -X POST -F "image=@/path/to/your/test-image.jpg" https://your-ad-revive-upload-url.com
  

  If this times out, you know the issue is network-related, not application-level.

3. Verify Upload Directory Permissions & Ownership #

Even with 0777 permissions, if the upload directory is owned by the wrong user (not the web server process), uploads will fail:

• Find your web server user (usually www-data for Apache/Nginx, nginx for Nginx-only setups)
• Change the directory ownership:

  chown -R www-data:www-data /path/to/your/ad-revive-upload-dir
  

• You can revert permissions to 0755 after fixing ownership (more secure than 0777):

  chmod -R 0755 /path/to/your/ad-revive-upload-dir
  

4. Check Server Disk Space #

If your server's disk is full, even with correct permissions, you won't be able to save uploaded files. Run this command to check disk usage:

df -h

Look for any partitions with 100% usage—free up space if needed.

5. Check Web Server Error Logs #

Don't rely solely on Ad Revive's debug.log—check your web server's error logs (e.g., /var/log/apache2/error.log or /var/log/nginx/error.log) for more detailed errors related to file uploads. These logs might reveal hidden issues like missing directories or permission denials.

Final Notes #

The PHP warning in your debug log is a separate, non-critical issue that you can address later by updating the HTML_QuickForm library or modifying the method signature to match the parent class. For now, focus on the network, PHP config, and server environment fixes outlined above—those are the most likely causes of your upload timeout.
