I'm having an issue with the menu items. Under Manage, I get no options for the menu tree items. Under the '1.index', '2.galleries' and '3.examples' links, the settings tab and the gallery tab both have no objects under them. However, for the '4.contact' I get options under 'Settings' and 'Gallery' shows 'No files and folders'. I've tried different browsers with no luck. Using the demo site, everything displays/acts correctly to the best of my knowledge. The 'upload' and 'new' buttons also do not work. I'm unable to delete anything from the default install under these menu items.
Turning X3 Diagnostics on shows the 'Everything seems to be OK!'. I've tried removing all files from the web server and reinstalling using the x3_installer.php file. Everything looks to install correctly. I can get in, make changes in under the 'Settings' tab, but nothing under manage.
Ubuntu 16.04
Apache2
Php7
X3 3.24.2
Any help would be greatly appreciated.
