Hi,

this problem happens when there is installed some plugin duplicating SQL queries execution during the installation of extensions.

Check if you have installed a plugin named 'System - MightySites', that could be the problem.

Hi, probably a plugin acting like MightySites is installed.

Please contact me at This e-mail address is being protected from spam bots, you need JavaScript enabled to view it providing an admin account to identify it and complete the installation successfully

Hi John,

i´ve cleaned my database. There where rests of the older JSitemaps Installation.
Now i can install the new version of JSitemap Pro.

Thanks

Yes probably on broken old installation was the problem.
Cleaning the database solves the problem indeed.
