Themes page hangs on save
Hi this is my first post and first time using Contao, I have installed and updated to 3.5.24 without the demo. Followed a tutorial on contaowiki to create my first site but when I am on the Theme settings and choose the Template folder the settings do not save, the page just hangs with an overlay saying 'Loading'. the only way I can stop this is by refreshing the page.
I have read a post with a similar issue but as I have automatically installed Contao through my webhost I'm unsure where I can check or change anything to solve the problem.
I have already uninstalled and re-installed.
Any help would be appreciated.
