Hello @xbytes ,
The issue is probably caused by RAM memory limit configuration.
Because your WP_MAX_MEMORY_LIMIT is set to 512MB (which is default value and you need to override it in wp-config.php) our plugin think that there is 512MBs of free RAM memory, but in reality there is hard limit of 40 MBs, best solution for you would be to increase memory limit to 512MBs in your php.ini configuration, that would resolve all issues or set correct value for WP_MAX_MEMORY_LIMIT in wp-config.php to “40M”.
After all running WordPress with only 40 MBs of RAM is quite challenging and may make the website unstable.
You need to increase the memory_limit variable in your php.ini configuration, most recommended value for you is “512M”.
Let me know if you can do that or you need more details of how to do it ??
Thank you!
