Why in modx revo after transfer to another hosting page manager throws 500 error?
The main page is displayed, but without some data, such as additional fields.
In the logs shows:
PHP Fatal error: Uncaught Error: Call to a member function getMessage() on string in /home/maks/myprojects/modx/core/model/modx/modmanagercontroller.class.php:617\nStack trace:\n#0 /home/maks/myprojects/modx/core/model/modx/modmanagercontroller.class.php(556): modManagerController->getDefaultState()\n#1 /home/maks/myprojects/modx/core/model/modx/modmanagercontroller.class.php(137): modManagerController->registerBaseScripts()\n#2 /home/maks/myprojects/modx/core/model/modx/modmanagerresponse.class.php(74): modManagerController->render()\n#3 /home/maks/myprojects/modx/core/model/modx/modmanagerrequest.class.php(183): modManagerResponse->outputContent(Array)\n#4 /home/maks/myprojects/modx/core/model/modx/modmanagerrequest.class.php(131): modManagerRequest->prepareResponse()\n#5 /home/maks/myprojects/modx/manager/index.php(58): modManagerRequest->handleRequest()\n#6 {main}\n thrown in /home/maks/myprojects/modx/core/model/modx/modmanagercontroller.class.php on line 617

Check what your PHP version. Try to put higher version. How to replace - clean the cache manually and try to open again.
