I uninstalled the Nicepage plugin in Joomla after I had problems with the menu on my website. I made a menu in Joomla with all of the articles, but it wouldn't show when I opened the website in the browser.
I wanted to uninstall Nicepage and reinstall it because I thought it would fix the problem, but immediately after that I got the following error on my Joomla account:
Failed opening required '/customers/4/7/9/kabot.be/httpd.www/leercentrum/administrator/components/com_nicepage/library/loader.php' (include_path='.:/usr/share/php')
I can't do anything anymore in Joomla and I don't know what to do about it.
