I also have faced this issue so many times while working in CRM, So today i would like to share the Resolution of below error so that in future anyone who is getting this error could rid of with this error :
Error while opening any record from my custom entities in crm 2011/2013.
This is most likely a IE Compatability issue. Add the server address in the compatability view under IE settings:
Go to Tools, if you are not able to see Tools option in IE Press \’Alt\’ key from keyboard. then select \’Compatibility View settings\’ like below :
Add your organisation URL or Server Address like below:
In Somecases if you are not using Mobile form of your Custom Entities, UnCheck \’Mobile Express\’ option will also be the way to get rid of from this problem. see below:
Congrats you will never face this issue again……..Enjoy 🙂 \\A/
