OK, so the error is related to VersionX calling on the user_view permission as it loads the 'Versions' tab (as opposed to anything going on in the MODX core). This one had me stumped for a while too!
In my case, I want access to that tab as administrator, but I'm not actually wanting my users in the affected permission group to be able to see it.
If you're in that position, here's how to hide that for your users. These instructions are specific for the 2.3 manager layout - everything is likely to be in a different place in other versions, but the underlying concepts still apply.
(Apologies if these instructions are over-simplified for your experience level - I like to give answers with heaps of detail because I know how helpful that was in these forums when I was a beginner!)
To stop the Versions tab from loading for your users when they're editing Resources
- go to the top-right cog menu > 'Access Control Lists'
- select the 'User Groups' tab if not already selected
- right click the group you want to have the tab disappear for and choose 'Update User Group'
- select the 'Settings' tab if not already selected
- click 'Create New'
- fill in the details as follows:
Key: versionx.formtabs.resource
Field Type: Yes/No
Namespace: versionx
Value: No
- 'Save' in that window and then 'Save' in the manager page
- your users will likely need to log out and back in to see the affects of this permission update - you can expedite that by selecting 'Manage' > 'Logout all users'. Keep in mind this will kill their sessions cold - they may lose data if they're in the middle of something and haven't saved.
If they also have access to edit things that aren't resources (such as templates, chunks, snippets etc), you'll need to repeat the above steps for each thing they have access to. The relevant keys to add instead of versionx.formtabs.resource are versionx.formtabs.chunk, versionx.formtabs.plugin, versionx.formtabs.snippet, versionx.formtabs.template, versionx.formtabs.templatevariables. Hopefully it's obvious what applies to what!
From there you're free to go back and edit the relevant access policy for the group and remove view_user permission because they won't need it with that tab not loading.
Now, if you want them to maintain access to VersionX but not see the menu item in the manager, I'm working on a solution to that which I'll report below when I have it.
