Re: Attaching files to Wiki site
Check your tiki admin control panel, for gallery uploads go to /tiki-admin.php?page=fgal, and for your attachments at /tiki-admin.php?page=wiki&cookietab=2&highlight=feature_wiki_attachments
and make sure you have your files uploading to a directory instead of database.
Once you have those checked off, make sure your directories are one level up outside of your tiki root installation, I like to create a folder called "files", and inside create one folder for each "gallery" and "attachments".
Back in your File Galleries and Attachment directory settings where you show the path of your uploads, should look like this:
../files/gallery/
../files/attachments/
In your check script you show 1MB for uploads, that is really low, you should have it at 32MB to allow files greater than 1MB to upload.
