I'm getting this error whenever I try to save/save & close/close in the Template Styles section of our site. I'm not experiencing it anywhere else. Can't say for sure how long it's been like this, because I haven't needed to touch that section of the site in a couple of months.
The most recent version of Sophia is installed and the site is on J5.4.10. I've cleared caches, tried different browsers, etc.
Any ideas where the problem might originate?
Thanks!
