Have you tried registering at makeabackup.com and asking about the error message there? Or email them if there’s a “Contact Us” link on their site.
They will probably be more familiar with their own error messages than us.
As for attachments limits, do you mean here on CDF? If so, this is taken from the forum FAQ…from what I know, you will be notified when you try to attach something that’s too large.
The administrator may allow you to use the attachment feature of this forum, which gives you the ability to attach files of certain types to your posts. This could be an image, a text document, a zip file etc. There will be a limit to the file size of any attachments you make, as the forums should not be used as an extension of your hard disk!
To attach a file to a new post, simply click the [Browse] button at the bottom of the post composition page, and locate the file that you want to attach from your local hard drive.
Only certain types of files may be attached: these are the valid file extensions for files to be attached to this forum: bmp doc gif jpe jpeg jpg pdf png psd txt xls zip.
After posting, the attachment will show up in the body of your message. To view the contents of the attachment (if it is not already displayed) simply click the filename link that appears next to the attachment icon
If the attachment question was about makeabackup.com, again you’re better off asking there.
Edit: OK, this is what I found when I Googled Default PLESK page. It’s not looking good!
