Code:
# This is an example of a basic feed, If you dont understand why all
   #   the \'s are in the examples below use this one as a template.
   set rss(bbcworld) {
      "url"         "http://ircdnevnik.wordpress.com/feed"
      "channels"      "#chat"
      "database"      "./scripts/dnevnik.db"
      "output"      "[\002BBC News\002] @@item!title@@ - @@item!guid@@"
      "trigger"      "!news"
   }


RSS Error: Invalid feed database file format (./scripts/dnevnik.db)!

Share a link to the script to have a look then.

This issue appears to be standard now. Sad
I'm using TCL 8.6 with Eggdrop 1.8 and have this exact issue.

At a guess, I would say that you started with..

RSS Warning: couldn't open "./scripts/feeds/<name>.db": no such file or directory.

Following that, attempting to make the <name>.db manually, resulting in your error:
RSS Error: Invalid feed database file format (./scripts/<name>.db)!

For me with the first "no such file or directory" also has a second error with it:
RSS Error: Unable to decompress "http://rss.slashdot.org/Slashdot/slashdot": zlib error (decompressor): invalid stored block lengths


There is a fix for the above zlib decompressor error: (changing the rss-synd.tcl file so use the built-in decompressing which was changed in TCL 8.6) but that appears to be broken too (well for me any way).

This is that fix if anyone is interested:
Changing the rss-synd.tcl by removing the # decompress gzip formatted data lines with the following

# decompress gzip formatted data
proc ::rss-synd::feed_gzip {cdata} {
return $cdata
}

I'd love any help too on getting this working.

Yes, the forum has a way of breaking the "\<newline>" sequence of chars.

When you cut the code from this page, the forum adds a <space> char at the end of each line, before the <newline> char.
That breaks the script by changing "\<newline>" to "\<space><newline>".

You can make that script load fine by searching the script for ALL lines that END with the "\<space><newline>" sequence & REMOVE the <space> at the end of ALL those lines.

Goodluck:)

Here is a copy of that script I have tried to make "forum safe".
It does not use the "\<newline>" sequence of chars at all.
Code:

#     written in TCL. Supports multiple feeds, gzip compressed feeds,
#     automatically messaging channels with updates at set intervals,
#     custom private/channel triggers and more.
