Hi,

Could you please enable the Debug (from the Global Configuration & Plug-in Manager > Debug) so you can see/share where is the SQL query/issue (it will be at the top of the stack trace)

Thanks,

hi. Seeing you,I believed in my project. Come back - my renaissance :) 

I will do debugging. Testing Seblod4. I secured myself for a second installation of Seblod4. Once I uninstall Seb4, I cannot re-install Seb4 a second time. You need to go back to the Joomla restore point from before installing Seb4. At this stage, you cannot uninstall Seb4 and create the project further. While waiting for Seb4, the project must be done from a Joomla restore point without Seb4. There are errors when installing Seb4 the second time.

do you need it?
