Solution to Fatal error: Call to undefined function low_get_cache() in ft.low_variables

shinymuhammed 17 May 2017 11:24 problem, complete

Upgraded EE website from 2.5.5 to 3.5.4.
Upgraded Low Variable to version 3.0.4 from EE3.x CP.
EE CMS site front and back end loaded correctly after up gradation.

Only problem is that interface of structure add-on pages tab content is not loaded properly.(Support request sent to structure support team).

When I click on any entry on the pages content,Edit Entry page is not loaded with proper interface and on the bottom of that page shows the following Fatal Error.

Fatal error: Call to undefined function low_get_cache() in C:\xampp\htdocs\intranet-backup\system\user\addons\ low_variables\ft.low_variables.php on line 200


Screen shots attached.......



How can I remove this error?

    Are all extensions enabled?

  2. shinymuhammed 17 May 2017 11:48

    yes,all extensions used in EE2 are enabled in EE3.

    Screen shot of add-on manager attached.

    Installed doesn't always mean Enabled.

    In the CP, check Developer > Utilities > Debug extensions.

    If no extensions are found, the 'allow_extensions' setting in the config is probably set to 'n' (should be 'y').

    If there are extensions, make sure the Low Variables extension is enabled.

    No extensions are found in CP, Developer > Utilities > Debug extensions.

    When I turned on $config['allow_extensions'] = "y"; in config.php, log-in window of front end and CP is coming and after login, website and CP is not loaded shows only the message " Invalid file request ".
    what is the solution to this problem?

    Probably another add-on causing errors.

    You can try and disable all extensions (except LV) manually in the database, by opening up the exp_extensions table, setting all 'enabled' rows to 'n', except for the rows that mention Low Variables.

    Turn on the other extensions one by one to see which one causes the trouble.

    Thanks ........
    LDAP authentication add-on causes the error. Deteted this extension from
    exp-extension table and set $config['allow_extensions'] = "y" ,then ,Edit Entry page is loaded with proper interface and the fatal error got resolved .

    But again interface of structure add-on, pages tab content is not loaded.( Support request sent to structure support team ). Do you have any suggestion regarding this?

    Not really no. That's a Structure issue, not a LV one.
