Forbidden
You don’t have permission to access /panel/indexpl.php on this server.
So i was just on my phone making a error pages then that message popped out i keep trying and trying it just says that message i tried relogging in nothing just works i cant make a error page
Where did you see that error and after doing what? And I don’t think if you need to setup error pages since you are using wordpress.
oh ok thanks
I know Softaculous complains if there is already a .htaccess file
to not accidentally overwrite the existing one during some installation
for the control panel I’m not sure 
but,
you are somewhat lucky that the control panel threw out that error
and you were not able to edit .htaccess to redirect error pages (via the control panel )
because it could easily happen to break your WP
if something is written incorrectly in .htaccess of WP
