Page edit mode doesn't load
26 May 2015, 10:42
Hi,
One of our students has come across an issue with the edit view of a page doesn't load. It simply showing "loading" but the page never loads. The display view of the page seems ok. When she tries to change the layout, it says:
"A nonrecoverable error occurred. This probably means you have encountered a bug in the system"
When I check in the error log, here is the message in the log:

=======================================
Has anyone here come across such issue? We are on Mahara 1.8.3. Any idea how we can fix the page?
Kind regards,
Shen

Hi Shen,
Sorry for the late reply.
I'm not sure if you've fixed this problem but the error looks to be due to you wanting to save a block on a page and there is already one existing at the same view/column/row/order position and so the database is throwing the error as it can't have two blocks in the exact same position.
But how it thinks that is the mystery.
Are you able to check the database table block_instance to see what blocks are attached to the view? There might be some corrupt data?
Cheers
Robert
