[opencms-dev] Error importing modules

[Gonzalez, Arnau (GE Consumer Finance, consultant)]

Hello,

The same error appears always I want to import a module:

Error publishing folder "/alkacon-documentation/javadoc/core/org/opencms/cache/".
Exception org.opencms.file.CmsVfsResourceNotFoundException: Unable to read folder with ID "... a long number..."
 ......

Could anybody help me with this?
