Issue #1 - Photos. Somehow, sometimes, when I added a new author's photo, it overwrote a previous author's existing photo - so the new photo showed up with the correct author as well as alongside a preexisting author's bio, blurb, etc.
Hi,
You mean that if you have 2 authors A and B and you upload a photo for B it shows in A too?
It's really weird. First time I hear about this. I think it could be a cache problem. When it happens again please clear your cache or try with a different browser.
Issue #2 - Suddenly can't save anything in the authors component. I can edit an existing author, but when I click SAVE, it doesn't do anything and then none of the other buttons work either (apply, cancel, nothing.) I can see them, but they aren't clickable. I have to kill the browser window and go back into the page again. Same thing happens when I try to add a new author - I can fill in all the blanks, but can't save any of my data.
It could be a js conflict with other extension you have installed. Please check if you are using a different WYSIWYG editor. If you are, try with Joomla! default editor and check if the problem persists.
Best regards,
