Hello Pierre,

After spending hours checking your site, the problem is coming from your system plugin "ijseo". It is trying to use a non existent function when it the content plugins are triggered at the back end. As soon as I turn off "System - iJSEO", the page is working correctly now.

Here is the full stack trace of the error:

Fatal error: Uncaught Error: Call to undefined function mysql_escape_string() in /home/hlcommun/public_html/plugins/system/ijseo/ijseo.php:901 Stack trace: #0 /home/hlcommun/public_html/plugins/system/ijseo/ijseo.php(842): plgSystemIjseo->updateRank('0', 0, '2017-01-02 07:3...', 'healthcare it n...', '0') #1 /home/hlcommun/public_html/plugins/system/ijseo/ijseo.php(764): plgSystemIjseo->getKeyRank('healthcare it n...', '0', '2017-01-02 07:3...', '0') #2 /home/hlcommun/public_html/libraries/joomla/event/event.php(69): plgSystemIjseo->onContentPrepare('easyblog.blog', Object(EasyBlogPost), Object(Joomla\Registry\Registry), 0) #3 /home/hlcommun/public_html/libraries/joomla/event/dispatcher.php(159): JEvent->update(Array) #4 /home/hlcommun/public_html/administrator/components/com_easyblog/includes/triggers/triggers.php(43): JEventDispatcher->trigger('oncontentprepar...', Array) #5 /home/hlcommun/public_html/administrator/components/com_easyblog/includes/post/post.php(4079): EasyBlogTriggers->trigger('prepareContent', Object(E in /home/hlcommun/public_html/plugins/system/ijseo/ijseo.php on line 901
