I cleared the schedule history. I then edited the job and resaved it. The errors are still thrown every minute as I write this. Three errors are thrown every minute. There are no other errors in between them, so I assume these are all the errors logged for the each fail. I am using US english as default. I have used GB in the past but currently is disabled. I did try to upgrade to version 6 on a local machine but I ended up with more problems than it solved so I prefer to stick to 5.6.3 for time being on the live site.

One more thing. There is a folder /Portals/X/Cache . It has a Pages folder with various attrib and data files. There is a modules folder which is empty. In the root there are various files such as TabModule_1646_en-US.resources or TabModule_1764_en-GB.resources.

I am not sure why there are GB files there. Could these be the cause of the problem? Is it a good idea to delete these files to clear them and so the system can regenerate all the cached content? How do I know which portal is the error from? Should I delete these files in all of the portals?
