can't change the theme to my smf forum

[ovidole91]

Hello  there !

i have isntalled Connect theme on my smf forum, but when i try to install and change to another theme, the main page of the website, the one with the portal and the other one with the forum are looking ok, but when i try to go into topic from the forum, it is changing to Connect theme template that was before,and not the one of the active theme that was set up.

This is the same with all the themes that i have tryed to install and apply to my forum.

Please help me and tell me what i could do to fix this issue  ?

Thank you !
