upgrade 4.7.3 > 4.9.0 : Error in modules tab

[Niels_B82]

Hi all,

 

Just tryed tot upgrade my 4.7.3 install to 4.9.0.

 

Upgrade went well untill I went tot the modules tab to reactivate the modules that were disabled during upgrade.

 

When opening the modules tab I get the following error:

 

Warning: key_exists() [function.key-exists]: The second argument should be either an array or an object in /sites/.../www/classes/AdminTab.php on line 227

 

Result of this error is that I can't see any of the modules.

 

I checked the AdminTab.php file with te file used in the 4.7.3 AdminTab.php file en there were no differences between the 4.9.0 and the 4.7.3 file in this section.

 

Any ideas how to fix this?

In the mean time I rolled back to the 4.7.3 install and luckily that still works fine.

 

Thanks in advance for youre input.

Niels
