Cannot edit fields in Studio – error Failed to retrieve data

[Cadej]

When I go Admin → Studio → Accounts → Fields → an error pops up - Failed to retrieve data

When I try to edit Fields in any Module in Studio I get this error.

When I click on Studio → Accounts → Relationships. The relationships open, but I cannot add a relationship. → an error pops up - Failed to retrieve data

I can edit other components e.g.
Labels, Layouts, Subpanels
Studio > Accounts > Layouts > Edit View
Studio > Accounts > Layouts > Detail View
…

---

Another strange bug.
When I click Studio > Accounts → an error pops up - Failed to retrieve data. If I then click on Labels, Relationships, Layouts, Subpanels, nothing happens.
I have to go back to studio and then one again Accounts and then Labels. Then I can edit Labels.

Thank you.

Hi @Cadej,

Yet again, thanks for the feedback.

Could you send a screenshot of the error, please? and also check the browser’s network tab and console to see if there are any errors?

Could also check your legacy .htaccess please? In public/legacy/.htaccess

If your vhost is directly pointing to SuiteCRM’s public folder, the RewriteBase on the above file should be something like:

    RewriteBase /legacy

if your instance is at https://<some-host>.com/subfolder/

The your RewriteBase should be:

    RewriteBase /subfolder/public/legacy

Please let me know if this helped.

[Cadej]

The content of initial .htaccess installed file:
RewriteBase /public//legacy

The console errors after pressing the »Fields« icon in Studio - Accounts:
I’ve also clicked around the SuiteCRM. Logout, login, cleared cache, clicked around Studio. I’ve got 3 different errors in console after click on the »Fields« icon in Studio – Accounts (the difference is in the last line).

I tested several values and tested each one:

RewriteBase /public/legacy

RewriteBase /public_html/public/legacy

![Notification 02 failed|690x200](upload://snrn5RQOv1RTquBpsftzjIgT51G.png) ![Notification 02 failed|690x200](upload://snrn5RQOv1RTquBpsftzjIgT51G.png) ![Notification 02 failed|690x200](upload://snrn5RQOv1RTquBpsftzjIgT51G.png) ![Undefined|690x263](upload://3u00z22WwOl7lp1mW5zQalLWDeP.png)

In every version I’ve also got those errors in console (posted above).

After change in RewriteBase new pop-up appeared in Studio saying “undefined”.

Hi @clemente.raposo @Cadej ,

Below line in view.modulefields.php is giving error - Uncaught Error: Attempt to modify property “vardefs” on null., because mbvardefs is null, is it because of Php 8 ?

$studioClass->mbvardefs->vardefs[‘fields’] = $f;

PHP issue is reported here - PHP :: Bug #80535 :: Backward compatibility issue - FATAL error
