Hi Nienke
The column weight of -1 = the "Auto-fill" mode. Studio Pro only accepts it when the registered UI Resources version (manifest.json) is ≥ 4.0. If Atlas Core wasn't properly updated, it still reads the old version and throws error.
May be try by re-import Atlas Core 4.x from the Marketplace, then open themesource/atlas_core/manifest.json and confirm the version reads 4.x.x (not 3.x). Also update Atlas_Web_Content and Atlas_Native_Content to their latest releases a version mismatch keeps the registered UI version stuck.
I hope this helps!!
Hi Gurumoorthy,
Thanks for your response! Unfortunately, your solution did not solve the issue.
In the meantime, we have found another solution. The issue was that, to clean up the project, we cleared the theme folder. It turned out that the settings.json was located inside, which is necessary for Mendix to determine whether the Atlas theme or another theme is being used. Missing settings.json leads to the layout grids to be broken, because a certain value cannot be retrieved.
Kind regards,
Nienke
