I'm currently running a trial of a VPS system using Plesk 7.5.4 with a view to moving all my accounts from my shared hosting. I have a piece of php software (Reciprocal Manager) that runs perfectly on my shared hosting system but won't let me manually add links on the VPS. The software will access the database and restore a text backup to the db from the shared hosting and will allow categories to be added to the database. However it appears to be saying that a URL that it is trying to verify as existing, is either not there or is mispelt. The software troubleshooting says try restarting apache. I've tried that with no luck.
