I tried going to "css_includes.html" and changing the "/.../" part to the absolute path as shown in the error message, but then instead of the Whitelist my ACP shows only a page with two buttons, Submit and Reset at the top, and nothing else.Fatal error: Uncaught Twig\Error\LoaderError: Looks like you try to load a template outside configured directories (@robertheim_topictags/../../prosilver/theme/rh_topictags.css) in "@robertheim_topictags/css_includes.html" at line 16. in /home/mysite/public_html/phpBB/vendor/twig/twig/src/Loader/FilesystemLoader.php:291 Stack trace: #0 /home/mysite/public_html/phpBB/vendor/twig/twig/src/Loader/FilesystemLoader.php(209): Twig\Loader\FilesystemLoader->validateName('@robertheim_top...') #1 /home/mysite/public_html/phpBB/phpbb/template/twig/loader.php(135): Twig\Loader\FilesystemLoader->findTemplate('@robertheim_top...', true) #2 /home/mysite/public_html/phpBB/vendor/twig/twig/src/Loader/FilesystemLoader.php(150): phpbb\template\twig\loader->findTemplate('@robertheim_top...') #3 /home/mysite/public_html/phpBB/phpbb/template/twig/environment.php(328): Twig\Loader\FilesystemLoader->getCacheKey('@robertheim_top...') #4 /home/mysite/public_html/phpBB/cache/production/twig/d5/d580fee0d626eae3c6388240acf65baf372928794d4462b1b in /home/mysite/public_html/phpBB/vendor/twig/twig/src/Loader/FilesystemLoader.php on line 291
The answer is probably some simple tweak that the experts wil know. Can anyone please help? I'm handy with CSS and HTML, but php is barely legible to me.
