I finally managed to generate the source code
Here is how it is done in case someone is experiencing the same problem of generating source is taking too long:
thanks to Beachbone for pointing out the direction on how to reset the queue. However i found the below post tackling the same issue:
I decided to turn off the cron scheduler as mentioned above. Backoffice >Settings > Advanced > Cron > disable cron=yes
on hosting panel contact database > phpadmin
click database on the left sidebar
click Search on the top menu
search for the following without brackets (source_queue) > sellect all > Go
the result should show a table with the source_queue row (at least one positive result). click the row in question to edit as follows:
- click delete to reset the queue
go back to Siberian editor and refresh the page. if every thing is done properly you should be able to generate source code with no problem.
