On Dragonflight Pre-patch PTR my addon gives me six errors of the type “4x Unrecognized XML: AbsDimension”. I can’t find anything on the Internet about how to change my addon to fix this. Or is it an error in the 10.0.0 Pre-patch? There was no problem with 9.,2.7 on the PTR. Posting here because “New Topic” button doesn’t seem to work in the appropriate PTR forum.
Is your addon specifically for Dragonflight? If it’s not, then I would assume there will be problems.
try this… move the Interface folder from the retail folder to the desktop (this will make the Addons be disabled) then add the addons one at a time to see if the error returns on any of them . if one or two are found leave them out intell the addon(s) are updated on curseforge
Almost all addons that I would normally use have multiple errors in the Dragonflight Pre-patch PTR. I have verified that the one addon that I develop has errors. I fixed a number of those errors, but some still remain, of the type indicated in my post.
I should have made it more clear that this is an addon that I maintain. It worked fine in the PTR 9.2.7, but has errors in PTR 10.0.0. So this is me trying to get it to work specifically in 10.0.0. FWIW the addon actually works as expected despite the six errors mentioned. Those six errors get WoW complaining about a high error rate.
Oh I see. Good luck with your addon 
Solved. The latest version on the PTR includes additional information about the error, particularly about the file and line where it occurs. This extra information was enough for me to work out that an ‘Anchor’ must now be within an ‘Anchors’. That wasn’t a problem for the previous dozen years, but is with 10.0.
