Server keep giving me 403 Lite Speed Webserver error page, at below page of Lumise WordPress Plugin, when user checkout in ajax request on longer request only.
https://therenaissancemarket.com/personlize-designer/?product_base=6&product_cms=30262
I tried to analyze and found it comes on more than around 664082 bytes in content length or for longer post variables
I check phpinfo() and found
max_input_vars 1000
post_max_size 128M
upload_max_filesize 128
opcache.max_file_size 0
realpath_cache_size 4096
but its keep giving lite speed 403 web page.
then i disable mod_security just to be make sure that it is not cause of this.
But still issue is there 🙁
Can you guys please help me on the following?
1- Is there a way, we can see what causing 403 error for debug, i.e: post size or input vars or what? instead of 403 page so i can sort it?
2- Or if there is any specific configuration i need to set on Lite Speed?
By the way, server having details OpenLiteSpeed, Direct Admin Panel on Linux.
Below are the Logs I see on Mod_Security in Direct Admin Panel which shows the same ajax request, as shown in the image, 
Following is 1 of the Log details.
