Hi @daskreativlabor
No, It is not a known issue. Mostly, one of the settings below might have an issue with another plugin. Can you please try disabling them one by one and check?
1) AIOS > Firewall > PHP Rules – WP REST API Can ou please uncheck the Disallow unauthorized REST requests:
2) Deny bad query string – AIOS > Firewall > PHP rules tab. URL Security – Deny bad query strings: uncheck the checkbox and save
3) Advanced char filter – AIOS > Firewall > PHP rules tab. – String filtering Enable advanced character string filter :uncheck the checkbox and save
4) 6g firewall rules – AIOS > Firewall > > PHP rules tab – nG firewall – Enable 6G firewall rules – uncheck the checkbox and save
5) 5g firewall rules – AIOS > Firewall > 5G Legacy firewall rules tab. Enable legacy 5G firewall protection uncheck the checkbox and save. ( This tab will be visible only if futurue enabled in past, It is deprecated in recent AIOS version.)
If the above disabling settings do not solve the issue, can you please add the below constant and check if it solves the issue, then let me know. I’ll check on my end.
define( 'AIOS_NO_FIREWALL', true);
Regards
