Hi guys

Hope you can help me.

One of our content editors reported yesterday that he couldt access one of our websites.

We keep getting the error "Failed to enter lock within timeout"

[TimeoutException: Failed to enter the lock within timeout.]

I tried deleting the umbraco.config and the TEMP folder with no luck.

Does anyone have any suggestions to what I could try next?

We're running Umbraco 7.2.5 assembly: 1.0.5610.18894

We have 4 similar sites with no problems

Hope you can help me out

Best
