I did backup the live website with Akeeba and installed this backup into a subdomain. Now the frontend is not working at all and I get an error:
An exception has been thrown during the rendering of a template ("Uninitialized string offset: 0".
I did clear cache and make sure path to temp and log directories are correct. The error still is there.
In Backend when I try to access GTiShop template in template manager I get:
Whoops \ Exception \ ErrorException (E_NOTICE)
Uninitialized string offset: 0
And Backend is not working anymore (I need to use the browser back button).
I did ask in Rocketheme forum and a staff member there told me, the problem must come from template, not Gantry:
I use Joomla 3.9.4 and Gantry 5.4.28 and GTiShop 2.0.4.
Any Idea of what can cause this and how to solve it?
Thank you very much!
