Joomla 3.9.13 with Helix 3 and P1 template.
I tryed to insert manually alt attribute to the logo in templates/P1/features/logo.php but after saved I receive an error message in frontend of the website and this also after upload of original logo.php.
To solve I uploaded the folder of template and the frontend of the website now is online.
The problem is that now when url points to a page that doesn't exist I don't see a page that inform that the page doesn't exist but I receive the following error:
*Warning: requireonce(/home/WEBSITEDIRECTORY/publichtml/libraries/joomla/document/html/renderer/head.php): failed to open stream: No such file or directory in /home/WEBSITEDIRECTORY/publichtml/templates/p1/error.php on line 42
Fatal error: requireonce(): Failed opening required '/home/WEBSITEDIRECTORY/publichtml/libraries/joomla/document/html/renderer/head.php' (includepath='.:/opt/cpanel/ea-php74/root/usr/share/pear') in /home/WEBSITEDIRECTORY/publichtml/templates/p1/error.php on line 42*
Please, somebody can help me to solve the problem?
Thanks.
