In Professional Edition, after the Spring '20 release, I'm not able to save any lightning component. Getting the below attached error. Anyone else facing a similar issue?
nested exception is: common.exception.ApiQueryException: select Id from Site ^ ERROR at Row:1:Column:16 sObject type 'Site' is not supported. If you are attempting to use a custom object, be sure to append the '__c' after the entity name. Please reference your WSDL or the describe call for the appropriate names.: Source
