Hi Ciaran,

I saved one of the J51 Elvira styles with a new name then tried to assign it to menu items. Sometimes I can get it to assign to 4 items if I select one then save, select another and save etc, but never more than 4 altogether and most often none at all.

It has worked fine when I last tried a couple of years ago but I have updated Joomla, other extensions and Elvira since then.

I have Joomla 3.9.2 with Elvira 1.0.1.

Sometimes but not every time that I tried to assign the styles today I had an error message "The security token did not match. The request was aborted to prevent any security breach. Please try again."

I have tried toggle selecting all menu items, doing it one-by-one, making a fresh copy of the original J51 style sheet, copying a different one of the J51 style sheets, clearing my site cache, logging out completely and clearing my browser cache, using Chrome, using Firefox, restarting my machine, all with no success.

System page cache is already disabled.

Any ideas what might get it to work?

Thanks for any assistance.
Suzanne
