Also, check your permissions on the cache directory.

Please post your error.

It's going to be the same error. It is a known issue. well at least known by me and Q not sure if Daniel admits it. Q said he thinks it's some sort of race condition in the cache, but I don't think anyone's taken the time to dig into it very much. It only appears to happen once every couple of weeks, so if you just turn display errors off it's not a huge deal, but it probably should be tracked down and eliminated before long.

of course if it's happening every page load then it actually is a permissions issue.

please be advice how can off / remove this warning???

Not sure what the cause is, could be related to the cache having expired, but your cookie hasn't? To get rid of this error message, just refresh your page. Simple, cache recreated, error gone!

Alternatively, to prevent display of this error altogether, log in to your admin, select "System->Settings" and click the "Server" tab. Under here you will find an option labelled "Display Errors:", set this to "No".

yes ...problemo solve .. thanks fido-x

No worries.

I've attempted more efforts at avoiding these messages in v1.4.9.3 .. still no full understanding of why.. some race condition I assume so trying to check it better

When you say race condition, do you mean a timing issue between when the cache is issued, checked and the server tries to access it?

I still haven't looked into oc cache system beyond seeing a few calls here and there.
What and when is going into the cache?
There's a bunch of files in my folder so, could it be:
1 per product
1 per information item
1 for the category
1 for the manufacturers
?

Maybe, it's time to go with an outside library?
