I will delete what you've told me to delete. With the valid expressions or what they may be called - I am stupid again... (I understand nothing from Perl and/or my English is not good enough)

Well, the cgi-welt directory: this server lets the user put their cgi-scripts anywhere, but not into cgi-bin (it understands it as its own, main, root etc.) OK, I can try with outside of cgi-bin.

But: in the mean time, I've builded a second version of links - links2. All was working, till I've uploaded the three files from backup: links.db, categories.db and email.db.

Maybe there is something wrong with them? Could they harm the whole "Links"?

What else? Oh, of course you could see "V" and "Z", but they was made before the bug "was there". Till this time, it was all working great...
