phpbb_usermap_poitable which led to Usermap's failure to correctly display search tabs and the overlay control element.
Usermap uses a modal window to allow (authorized) users to create a new POI. The HTML code for that window (and thus the form used to enter the data) was always included in Usermap's main window. If guests are permitted to view the map (e.g. to display POIs) anyone with the necessary knowledge is able to access the input form even if guests are not allowed to create POIs. To prevent this I have changed the
/ext/mot/usermap/styles/prosilver/template/usermap_main.htmlfile so if guests are allowed to see the map and are not permitted to create POIs this form will no longer be available.
This should solve the problem at least on a short term but I will look into this issue a lot deeper in the future.
All Usermap users (at least all who allow guests to see the map) are strongly adviced to download the attached file, unzip it, upload the contained file
usermap_main.htmlinto the above mentioned directory and purge the cache. Afterwards you should be safe from that kind of spam.
This file will be part of the next version of Usermap.
