I am new to using Joomla, I have a temporary hosting account on Demojoomla.
I have installed a template called Helix
When I go to Extensions > Templates > Styles I can click on my template and configure it, and save the changes.
Then, when I refresh the site, nothing has changed.
But when I close the template editing screen and refresh the page, I can see the changes, but only until I refresh again or choose a different menu option, then it reverts back to the old design.
If I then disable the template and enable one of the standard Joomla templates instead, when I refresh the page, the display reverts to the Joomla template, but if I then navigate to a different page, I get the Helix template back again!
Some links give my modified Helix template, others the default Helix template, others a standard Joomla template, it's pretty random and different each time. It's unusable.
Have I done something wrong in config, or is there a serious bug in Joomla?
