TV tab disappear after upgrading from 2.8.5 to 3.1.0

[letamtam]

Summary

After migrating from MODX 2.8.5 to MODX 3.1.0 I lost the TV tab on all resources created with differents templates

Observed behavior

When I open a resource or create a new resource, the TV tab is displayed on 2.8.5 version.

But on 3.1.0 if not present.

Programmatically:

• On MODX 2.8.5 $modx->resource->getTVValue(‘webnews.NrItemPage’); return a value
• On MODX 3.1.0 $modx->resource->getTVValue(‘webnews.NrItemPage’); return empty or null

Expected behavior

Tab with TV available

Environment

Apache 2.4.x / PHP 8.1.x

I tried it as admin member and sudoer, or as non-sudoer, same result.
I checked if settings is tvs_below_content is set to NO.
I checked on Manager customization : No form profiles are available
I checked the path of settings on config.inc.php
I can see the TV checked on the template available variables

Thank you for any help

• Are there any related errors in the MODX error log? Or in the “Console” tab of the developer tools in the browser?
• Did you try clearing the browser cache (and the MODX cache) after the upgrade? Maybe there is still some old file in the browser cache with the same name that gets executed instead of the updated code.
• Does the database table modx_site_tmplvar_contentvalues still contain the TV values? Do the resources in the table modx_site_content have the correct value for “class_key” (e.g. MODX\Revolution\modDocument for a normal resource)?

Thank you for your help.

• Error: nothing in error log
• Cache are cleared, I tried with “privat navigation”, I tried with another browser
• Yes for all, my TV appears on list of availables TV when I edited a template.

I tried a fresh install and no problem appear. I tried an update on my local server, it works fine.

I will try again with a fresh copy of 2.8 and try again to upgrade. Perhaps a problem occured during the update process.

This might not be of any help but I remember a similar problem with an older version of MODX where this would happen when an outdated tv type was used - something to do with list boxes from what I recall. I vaguely also remember having to go in and justsave each tv again after an upgrade.

Is this site using Form Customization to relable fields and position tabs? If so, is it possible you have stuff mapped to regions that may not exist any longer?

Hello thanks for your help @smashingred @chrisandy @halftrainedharry
I tested your proposals but it didn’t seem to be the same problem. Finally I restored a backup and reapplied the update to MODX 3.1 and it worked. Why did it work? I don’t know why. Probably a problem with the upgrade. Fingers crossed that it continues to work well
Thanks for your help, I’ve learned a lot.

@letamtam how did you do the upgrade? Did you do it manually on the server, using the Upgrade MODX Extra, Softaculous in cPanel, or in MODX Cloud using the Upgrade button?
