Hello if you are having problems with the “Custom Code” of Elementor Pro, I inform you that after a lot of research, I found the problem related to ModSecurity used by Cyberpanel, it is a false positive and it is already under review by the OWASP team:
There is still no solution, if not to disable the rule.
If anyone here comes up with a better solution, please help.
do not recommend modsecurity. Development stopped years ago. Kindly use an alternative WAF. I recommend CloudFlare for your website, Imunify for your server
For wordpress websites use WordFence premium, Sucuri or BPS. They all work like a charm
Seems like it’s in constant development, 4 will be released soon, using Sucuri on more than 30 sites is a headache, better to have a solution on the panel/server.
