Yes thats very odd because the image alt and title attribute are missing on the majority of the images that they were successfully added to. On the screenshot you sent thats one of the very few tags that hasn’t been deleted. Once this was done originally I proofed the changes in the source code and it was working correctly. Now the majority of my title and alt tags have disappeared. The only tags are are still there were the first two galleries added. I added all the tags to the images at a later time though successfully.
Any insight why this is not working correctly? I spent a lot of time doing this and made sure they were added by viewing the source code on every gallery.
I believe an update caused this error. Around 50 images still have the tags and around 450 image tags were removed. I made sure they were added correctly and triple checked my work.
I noticed this change when I was adding additional images and that most all my tags had been removed. Any tips to retain this data? Where would this metadata data be stored in the wordpress backup files? I only have my latest backup done a few weeks ago and not sure if it was done before this issue occurred. Do you think this is an update error or a plugin conflict with yoast seo for example?
