Had to INCREASE Maximum Request Size

Hi @fssbob ,

WP Migrate Support Team here, Thanks for reaching out with your query we would be happy to assist!

The Maximum Request Size is a setting used to combat issues related to low memory, reduce the memory being used or increase the memory that can be used. In your case, when you increased that setting, you allowed WP Migrate to use more memory when doing the export.

There’s a couple of possible reasons on why inceasing it resolved the issue for you:

If the request size is small, the plugin will need to make thousands of requests causing the export to hang and eventually crash. Increasing the Maximum Request Size prevents this by including more data on every request sent. 

Another possibility is if you’re being blocked and / or rate limited by your security plugin / software due to thousands of requests being sent by the plugin. Increasing the Maximum Request Size prevents this by also including more data on every request sent and decreasing the number of request sent by the plugin.

If this issue only happened recently, we suggest checking for any new plugins, theme, and server settings added/installed as it may have contributed to this. You can try and do a conflict check and temporarily disable those newly added software / settings then retry the export and see if that resolves the issue.

To find out what exactly caused this, we suggest enabling debug.log and reverting the Maximum Request Size to the default 1MB to replicate the issue you’re having. Once done, you can check the exact error from the debug.log file found on your /wp-content/ directory. If you’d like further insight on the error found, please feel free to forward it here so we can have a look.

Hope this clarifies! Please let us know if you have any other questions!
