I made a site earlier this year with Metropolis and placed a slideshow within the content using the loadposition method. Today the client rang and said that page is not loading at all, just showing a blank page. When I removed the loadposition command the page loaded (but without the slideshow of course). The only change I had made in recent weeks was to update to Joomla 3.3.6.
I posted my problem on the joomla.org forum and was advised to put back in the loadposition command and then upgrade the error reporting in global configuration to Maximum, then reload the page. I got this error message:
Fatal error: Class 'JFile' not found in /home/eq98972/html/modules/mod_j51slideshow/helper.php on line 25
I just now had a reply from the joomla forum person who said I should either add this before line 25 of your slideshow module
jimport('joomla.filesystem.file');
"or contact the developer". So I'll wait for your reply before fiddling around with the code.
