Make sure your plugin is up-to-date. Disable other or recently installed plugins as well as the JS error may not be caused by ACF.
Hello,
I started having the same problem today. Yesterday everything worked fine – I could upload the images, and today I don’t see the Image Upload button in my page editor. The header images on pages are still there, but I can’t add the new images and remove/edit the ones that are in place already.
I didn’t do any work on the website since yesterday, disabled all the plugins one-by-one to see if it’s some kind of conflict, activated and reactivated the ACF plugin – no result.
The website url that I’m working on is http://pulmonx.schipperweb.com/patients/
I’m having the problem with header images.
Your help is really appreciated.
Thanks!
Lara
