all subpanels disappear after linking a document to an account

Hello community,

i have a problem with the subpanels in de documents module.
If i link a document to an account, all subpanels disappear.
If i remove the document-link from the account, all subpanels appear again.
All other links are works as intended.

Does anybody have the same Problem, or an idea how to fix or analyze this bug.

I use Sutecrm V 7.10.9 with MS-Sql-Server

link to a screenshot (“Add File” Button won’t work)

and a link to the suitecrm.log

thanks for all the comments

Upgrade to 7.10.10 fixed this bug!!!
