Yes. There is something wrong with the ftp, I could not see the ajax-search-pro directory within the mappure.com/wp-content/plugins directory, but I managed to make changes via the admin panel.
The problem should be fixed now, however I have no idea what have caused it. There was apparently a PHP bug unrelated to the plugin, I will need to ask the PHP support about that.
In the meantime I replaced a bit of code in the search, it should work as expected now.Best,
