Hello, I have SP Page Builder 3.8.10 version with this system:

• Linux 3.10.0-962.3.2.lve1.5.73.el7.x86_64 #1 SMP Wed Aug 24 21:31:23 UTC 2022 x86_64
• mysql 5.5.5-10.6.17-MariaDB-log
• PHP 7.4.33
• Apache
• Joomla! 3.10.12 Stable

If I want to save a SPPB page, clicking on the Save button or the Save and close button will cause the system to waiting and not save the article. If I save a normal Joomla post or other SPPB page, there is no problem. Where does the process get stuck, why can't the system save the Page Builder article? How can I find out which item or data is preventing me from saving?

I get this message after page update. I tried it on two different machines: {"status":false,"message":"The most recent request was denied because it had an invalid security token. Please refresh the page and try again."} On Export button it says Restricted access, on Close button I get 404. Tried with Backend and Frontend editor too, no helped.

Update1: I solved the problem. In the RAW HTML block there was a script block (attached in the hidden message). When I took this out and put it into a separate script file, the save was successful without error. The funny thing is that for years before, there was nothing wrong with this block.
