The problem is that on a clean Opencart 2.3.0.2 I installed a template from Magentech ShoppyStore, ticked off admin rights, everything was fine. After that I installed Vqmod and put multimerch marketplace 8.9 on top, activated the module and immediately got out the following errors:
Warning: Unknown: Input variables exceeded 1000. To increase the limit max_input_vars in php.ini. in Unknown on line 0
Warning: session_start (): Cannot send session cache limiter - headers already sent in C: \ OpenServer \ domains \ shoppyfast \ system \ library \ session.php on line 30
Warning: Catch \ OpenServer \ domains \ shoppyfast \ system \ library \ session.php on line 50
Warning: Catch \ OpenServer \ domains \ shoppyfast \ system \ library \ response.php on line 12
And the admin rights have flown .. On other Magentech templates, everything gets up correctly. Please tell me how to fix these errors ....
