I tried changing .htaccess – not working. I also talked to my hoster – unfortunately also not working – output buffering is be possible on the server, memory limit is also high (>100MB). He thought that possibly connections plugin needs PHP 5.2 and is not compatible with 5.3 (as used on this site) – could this be the case? If not, are there any other things we could try?
Thx for your help,
