If you have module related error on login involving `userspace/OCA`, like:
```
invalid command name "module"
while executing
"module load userspace/OCA "
(file "/beegfs/home/<user>/.modulerc" line 2)
invoked from within
....
```
these are due to the fact that the module organization system has changed during the migration to the OpenHPC environement, And that module does not exist anymore.
**Solution:** flush or remove your `~/.modulerc` file and relog.
