I updated the plugin today and it seems to have resulted in a broken form.
The first issue was that the tabs in my forms had lost their labels but it didn't take long to reapply those.
The second issue was that when I updated the longer form I seemed to get a problem that may have caused a corrupted save. This may or may not be related to the update as the other forms are OK now I've fixed the tab labels.
I tried to use Pastebin to show the code but the lines from the exported form for post_content and post_excerpt failed to show when I copied it over there which further makes me think there's a corruption in the save.
I've exported the broken form and then imported it again and I get a report saying that it doesn't contain any fields which is why I think it's corrupted in the save.
This form has hundreds of fields so I really don't want to have to try and rebuild it from scratch.
Is there a good way to check the file and fix it if there's corruption?
Please download the MB AIO plugin version 1.12.3 here (removed link).
Then export the field groups (file .dat) and share them. I will try to import field groups to my site and check it out.
I've downgraded and here are the exports I get from both the older version and the latest versions installed.
In the older version the form works fine still. My current plugin versions are:
Meta Box 5.3.8
Meta Box AIO 1.12.3
Please update the plugin Meta Box AIO to the new version 1.13.2 then re-import the field groups file (.dat). Let me know how it goes.
I've just updated and the behaviour still isn't correct. Some of my forms load but with incorrect details (it seems mostly that groups and tabs are not showing properly or consistently). I also see that in the case of the form I shared above the version that was upgraded in place no longer opens and has the Show For value marked incorrectly as Posts while the version I exported and then re-imported shows correctly there as Users and does open but other forms (really simple ones even) don't open at all.
I'll roll back again for the moment.
Please update the new version of Meta Box AIO 1.13.3 to fix this issue. If the fields do not appear, please follow this documentation to migrate field data.
Still the same behaviour with that one. I upgraded and did the manual migration as per the doc and still no fields in the form. I did an import of the previously exported form file as well and the only behaviour difference is that it reports no fields in the form rather than just remaining blank.
Also worth noting that both the upgraded and the reimported forms altered their Show For setting to Posts rather than the correct setting of Users but both showed the settings correctly again after rolling back to 1.12.3.
Please see my screen record to migrate the field data https://share.getcloudapp.com/YEuXowEW.
I also shared the file "old-fields.dat" for testing https://drive.google.com/file/d/1M751DX23Ab4StOm8Gz1l2w5aPyKZ2yIK/view?usp=sharing.
Let me know how it goes.
Still no difference for me. Even using your example data I still don't get the fields showing and mine also doesn't get the Media option set for the Location like your video shows. Just the text stating there are no fields for the Fields tab.
The only other difference is that I don't have the Builder as a separate plugin but as you disabled yours in the video I assume that's not important.
Please share your site credentials via this contact form https://metabox.io/contact/. I will take a closer look.
I've just sent an update to the contact form as the issue still exists with the latest update as of today. I'd just left it on 1.12.3 while that was working.
