Creating new idea ends with white creen. And the log shows the following:

Just to confirm that the error also comes with all content types. Also editing the old content that was added prior to the update breaks them with the same error.

@Artmir does it happen for you also on a fresh install?

@zohar Just tested a fresh install. The issue is not present.
Seems this only happens when updating from 3.0.7.

By the way just tested the expert review and I think it is a great functionality. Kudos for this achievement!

Found the issue.
I was suspecting based on the error that this issue could be due to conflicted paths. I disabled pathauto module, deleted created aliases etc. Retried the update and now the site functions without issue.
Reinstalling pathauto after 3.0.8 does nothing. It doesn't work anymore. Need to look for a better alternative to create aliases...

Noticed an issue with the idea stats 5 star rating in full content sidebar after updating from 3.0.7 ->3.0.8. (I tried this update multiple times with the extra modules uninstalled, cache cleared etc. to rule out any incompatibilities)

When users visit the idea full content page, the users cannot see the 5 star rating in the idea stats, even though the five star is given by an expert. This happens only when updating from 3.0.7 -> 3.0.8.

There are two notices in the log files. Spent a couple hours on this but so far no luck what's causing this. Any idea why this may be thrown?
It is not a great issue but every time a usre visits the page 2 new logs are created which fills the log file very quickly.
