Hey. I can access ACP but can't access the main page.
Here's the error:
Fatal error: Uncaught phpbb\language\exception\language_file_not_found: Language file ./ext///language/en/language/en/blocks_admin.php.php couldn't be opened. in /home/username/domains/website.co/public_html/phpbb/language/language_file_loader.php:186 Stack trace: #0 /home/username/domains/website.co/public_html/phpbb/language/language_file_loader.php(143): phpbb\language\language_file_loader->get_language_file_path('./ext///languag...', 'language/en/blo...', Array) #1 /home/username/domains/website.co/public_html/phpbb/language/language_file_loader.php(103): phpbb\language\language_file_loader->load_file('./ext///languag...', 'language/en/blo...', Array, Array) #2 /home/username/domains/website.co/public_html/phpbb/language/language.php(643): phpbb\language\language_file_loader->load_extension('/', 'language/en/blo...', Array, Array) #3 /home/username/domains/website.co/public_html/phpbb/language/language.php(180): phpbb\language\language->load_extension('/', 'language/en/blo...') #4 /h in /home/username/domains/website.co/public_html/phpbb/language/language_file_loader.php on line 186
