[Edit: There has been a response. One of the problems has been fixed. Linkmachine is still behaving strangley from time to time with our new server settings but on the whole seems to be working again. Have not had a lot of time to test and check everything and will update here if there is anything of note.]
Well still no response from Linkmachine.
Have managed to get most installs working but the interface settings have dropped off again for one sites install and cannot be reset again.
Just tried Linkman but have not had any luck setting that up either. Seems there may be an issue with the maximum permissions settings allowed on the server.
I manually set up the settings.php file but the only page that was accessible was the link exchange input form. Entered a sites information, set up the reciprocal link on the other site only to get a message from linkman on submission that the link was rejected as spam.
Wasted too much time on this again today will search around for other options soon.
