We are now preparing to upgrade to Expression Engine 3.5.4 from EE version 2.5.5.

We are implementing up-gradation on local test server before implementing it on live server to make sure that we do not run into any issues.

Currently running structure Version 3.3.9 in EE 2.5.5 website is incompatible to EE version 3.5.4.

So we recently purchased structure version 4.1.12 from https://eeharbor.com/structure.

But when we are upgrading( as per the instruction from http://buildwithstructure.com/documentation/upgrading/) structure version 3.3.9 to 4.1.12 from EE2.5.5 website running in local test server shows the PHP Error.(Screenshot Attached).

Actually it is upgraded to 4.1.12 as per the screenshot1. But when click on module settings (screenshot2) shows this error and the same error occurred in the front end when we try to access the index.php.

Kindly send the solution as early as possible.

  • Also can you try this again passing $config['database']['expressionengine']['cache_on'] = FALSE in your config file? and check for above errors again?

$config['database']['expressionengine']['cache_on'] = FALSE - Not worked. solved the error by commenting two cases case 'get': and case 'set': in public function cache($mode, $key = false, $data = false, $persistent = true) of helpers/eeharbor_ee2_helper.php(Comment line no. from 228 to 237).After that error removed,front end loaded correctly, checked all links and they r working properly.In back end got the module settings page of structure 4.1.12.
