EE2 to EE4 white page

Hassan 31 Jul 2018 08:28 problem, rejected

I have upgraded cms system from EE2 to EE4 everything works fine but I have a problem with Low Variables addons.

if I want to adjust the setting then I get a white page. I do not know what is the problem, the version I use is 3.2.0.

do you know what is the problem?

   Can't say what's going on without an error message of some sort. Make sure you have the latest files in place and try these tips to turn on error reporting.

   I just installed Low Seg2Cat and I get this message:
   
   Notice
   Trying to get property of non-object

   That sounds like you're using an older version of Low Seg2Cat. Make sure you're on the latest version https://gotolow.com/addons/low-seg2cat

   I have just downloaded and installed version 3.0.0
   
   en i get this:
   You must define the following database parameters: database
   
   DBConfig.php:144

   Well, that doesn't look like an error caused by any Low add-on. Your EE installation might be corrupt or incomplete. Try and re-upload all files and contact EllisLab if this error message persists.

   Can't really help without an error message of some sort. That's a server issue, so try again and get back to me if you get error reporting working.

   I have looked at the code and I see the following.
   
   it looks like it’s failing on $input = $obj->display_field($var[‘variable_data’]); in the mcp file

   iget also this error in one of the low variabels that i use
   
   Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 20480 bytes) in /home/vda_dev03/codeIgniter_berry/ee/EllisLab/ExpressionEngine/Service/Model/Model.php on line 964

   That error message refers to not having enough memory on your server for PHP. That isn't a LV-specific issue.
   
   As for that line; are you getting an error message at all that referers to that line, and if so, what is the error message? If not, why do you think that like causes the issue?
