Thanks Alex for your message.

Connection string is fine and Umbraco back end section ({host}/Umbraco) works fine.

I rebuilt all Examine Indexes. And even tried to delete the TEMP folder. It has been recreated automatically.

The website page s still showing "The website is restarting message" and the log file is adding the line "Umbraco is not ready" repeatedly.

Hi Tom,

1. Have you tried logging in and publishing your root node?
2. Can you preview pages from Umbraco?

Thanks Simon for your message.

1.# - Yes, I tried publishing root node using right click and the dialog republish url

2.# - Preview page is not working. It shows the same error

It seems like there's an issue with ApplicationContext.Current.IsReady.

It is returning false when I checked...

Thanks Alex, I tried granting full permissions even to "Everyone" and the front end stays the same. I noticed it happening when I copy my project dlls but breakpoint debugging doesn't hit anywhere.. Really no clue...

Thanks Simon for your message. When installing a fresh install, this issues start to happen when i copy my custom dlls. One issue I could find was ambiguity between one of my project classes "MembershipHelper" with the new "Umbraco.Web.Security.MembershipHelper". I resolved all instances of this issue by providing absolute references.

But the issue still persists.
