Hi, to be honest I use SPPB for over 60 subdomains and works correct. The message with token can be from Joomla itself. It doesn't have to be from SPPB. So you have to double check if sessions setting in Joomla are correct.

Start from this: Are you able to login to front-end using Joomla Login component or login module? Use at least two different browsers to be sure that it's not a cache issue.

tip 2: Problems can be also if JCH_Optimze compression level is set too high. So it's good to disable that plugin (for testing period), clean Joomla cache and check again.

Hi Paul,

thank you for your replies.

Here are my answers to your suggestions:

• I am able to login thru the frontend. No problem.
• I tested on different browser. Same effect. I cannot edit my page with the frontend editor.
• There is no cache, no JCH extension.

Do you any idea about what could happens?

regards

Hi Paul,

I forgot to say that my sub domain is a copy of my main domain. All the SP Builder pages have been created in the main domain. The problem occurs when I try to edit them in the sub domain.

Maybe it can help you to give me solution for my issue.

Regards

We will add PHP 7.4 and PHP 8 full support soon. By now use lower version, PHP 7.3 is still valid & safe.
