Re: Solved but not understood, yet...: Fatal errors when upgrading to 15.2

posts: 98 Greece

It seems that I solved my problem while upgrading, but still I have not understood how such a problem could arise -and I mean the duplicate entries.

Let me explain why.

As I describe in the messages above, every time I was trying to upgrade I was receiving a duplicate entry error, which didn't let me connect to the database. The error was starting: Duplicate entry found (%CE%91%CE%BD%CE%B8%CE%BF%CE%BB%CE%BF%CE%B3%CE%AF%CE%B1+%CE%95%CF) etc. etc. A friend told me "why don't you look at http://www.url-encode-decode.com/ to see what these symbols are supposed to mean"? Well I checked and it was the first 10 or so letters of a few wiki pages of mine. Now, all these wiki pages are in Greek, but lets translate in english, so you will easily understand it, the pages would be "Science Fiction Bibliography (2014)", "Science Fiction Bibliography (2015)" and "Science Fiction Bibliography (2016)". Now, all these pages are different and of course they have different ID, so how on earth the database may be confused?? The easy solution was to change the titles to "111Science Fiction Bibliography (2014)", "222Science Fiction Bibliography (2015)" etc. etc. Then again the same error message with other wiki pages which started with the same Greek word, more page renaming and 10 pages later, I was able to upgrade with no error.

But: Is it really possible that Tiki or my Database may be confused by such a common thing, as wiki pages that start with the same Greek words but differ later in the title? Can't really happening... Right?

And how I will avoid it in my next upgrade? More file renaming?
