Adapt small php program to work with mediawiki 19.1

A small program used to assess dive sites and show the results in lists and clouds works fine on my site called [[login to view URL]][1] until mediawiki 17.5. Trying to upgrade my site to 19.1 an Invalid Marker error occurred for the divepoll part; the other components keep on working fine. Trying version 18.4, I noticed that the error already occurs with this earlier version. All files required have been uploaded. Please note that I had to comment out line 26 in the [login to view URL]: # $wgParser->disableCache(); for mediawiki version 19.1 (not so for the actually used version 17.5!) ...because it produces an error without doing so; I do not know why and wonder if this would have something to do with the Marker error.... **Task**: Adapt [login to view URL] to work without error for newest mediawiki version 19.1. ## Deliverables Please see attached files.
