Hello Ziaul,
Thank you very much for your support.
I have asked my server admin to look over according your feedback and by desactivating some rules, we manage to be able to save. Thank you very much for your help.
However, I face a new issue since I switched to Joomla 6 - SP 6.1 - Helix 2.2, I m not able to use the frontend editor anymore. I will try to explain, the frontend editor opens as usually, then I press Edit Page and I have 404 - Page not found then I press again to home start again and again 404 - page not found.
In the Hidden Content, I wrote you the access
May I kindly ask you to have a look?
Thank you for your help and support and sorry disturbing you soo much recently.
With my best regards,
Olivier
