I updated the site locally to version 4 of Joomla and the latest version of the component. Following the update the following addons prevent me from creating new article: - flipbook_gallery - grid_gallery - image_gallery, once deactivated I could create a new document. But on the site side, I have the following error:
Warning: preg_match(): Compilation failed: quantifier does not follow a repeatable item at offset 29 in /Applications/AMPPS/www/administrator/components/com_tz_portfolio_plus/libraries/template.php on line 417.
Thank you for your help
