Unable to show planning : error in jsonPlanning.php

Hello,

I upgrade screen customization plugin to V 7.0 this morning.
Since upgrade, i can't see planning : i get error in log (see attachment).

i try to reinstall V6.6 but still get error.
I reinstall V7.0.
Error persist.

I can see portfolio planning but not planning anymore :
 

 

Strange, after error occurs, can't close menu... even if i change screen (project or activity for example).
Need to deconnect/reconnect to be able to open / close lateral menu anymore...

If i open Planning another time after reconnect (and only planning, doesn't occurs with opening otthers screens), i'm stuck with lateral menu.

Probably linked to upgrade to scren customization plugin V 7.0.

I got the same issue when i open "screen customization" menu.
No error in log but lateral menu stuck...

Issue occurs only with admin profile.
*Works fine with others profiles...

Any idea ?

More and more strange !
Works with account admin, but not with MY account (admin profile). ?????²

Found an error in browser console (fireFox), see attachment.This error occurs only with my account, not with admin account.
