Cannot find variable type low_textarea

Xujie Zheng 1 Feb 2017 20:18 problem, complete

Hi,

We have encounter an issue where low variable cannot find the type. Our entire website is broken right now.

This is the php error log output:
[01-Feb-2017 15:07:13 America/New_York] PHP Fatal error: Class name must be a valid object or a string in /mnt/stor9-wc1-dfw1/659720/dev.c2c.grassrootsenterprise.net/web/content/manage/user/addons/low_variables/libraries/Low_variables_types.php on line 336

And the following is on the web page
Undefined index: low_textarea

user/addons/low_variables/libraries/Low_variables_types.php, line 331 hide details

Severity: E_NOTICE

   This should never occur, and I'm not sure how it could.
   
   I'd download a fresh copy of Low Variables, delete the files of your current installation, and re-upload all the files, making sure /low_variables/types/low_textarea/vt.low_textarea.php is there.
   
   Also re-save your Low Variables settings, making sure the Low Textarea type is indeed enabled. The checkbox should be checked and disabled, so you can't uncheck it.

   The error is still there after I reupload the folder

   Does this have anything to do with the database?Do you need access to check it out?

   This is the php Error log before and after I re-upload the folder

   Looks like the settings in the DB might be corrupted somehow. I should be able to determine that by looking in the CP (and its MySQL manager).

   If I'm not mistaken, this is the first error you get:
   
   

   unserialize(): Error at offset 287 of 417 bytes

   
   
   ...which points to an error reading the extension settings. So try and re-save the settings. If that doesn't work, I'll need to take a look myself.

   I'll need to take a look myself. Please send SuperAdmin login credentials to hi at gotolow dot com if you can.

   Xujie Zheng 1 Feb 2017 20:53

   it is sent, let me know if you need database access

   Xujie Zheng 1 Feb 2017 20:53

   or ftp

   This issue was caused by a manual find & replace directly in the database, thus changing the settings in a serialized array, which caused it the settings to be corrupted.
   
   Therefore LV couldn't read its settings and EE crapped out.
   
   Please, never manually change a serialized string in the DB; changing a single digit can cause errors like these.
