[Language Manager] Improve the warning message to make it more meaningful
When translating the pages, you might get the following error:
"Error occurs while translating content, please check the logs for more details."
Reason:
In most of cases, the issue happens when the page contains a block that was not enabled for the target language.
For an example: when translating a page from EN -> SV. The page contains a block in ContenArea. The issue happens when the 'sv' language is not enabled for the block.
Solution:
As the above example, please enable 'Sv' language for the block.
I think we need add more information to the message to make it more meaningful. It will help the customer understand the issue as we can't find more information in the log.
