Thanks Pascal, it's ok now !
I get this error too. Is there a fix or known reason?
I cannot save the General setting in 1.8.4. When I click on Save I get the following error:
"TypeError: element.input is null"
Can you fix it?
It's free ;-) http://www.sitemapx.com/
The problem with that is it's a Windows program, so you can't run it on your hosting and trigger it to run with a cron job. So you have to run it on your PC then upload it. The $29 version runs on the server and updates your sitemap/s and saves it/them wherever you want. It also makes separate Video, Image, Mobile, HTML, and text sitemaps too, it also has a lot of settings that can be customised to meet your needs.
Also if like me you run Linux on your home/office PC it also can't be used.
Okay I've found a solution:For me it worked when I commented that line out. Although its using our sites old site domain?
I've uncommented line 115 in /ow_system_plugins/base/init.php
$router->addRoute(new OW_Route('base.sitemap', 'sitemap.xml', 'BASE_CTRL_Base', 'sitemap'));
And now it loads the right sitemap. It seems the route to the sitemap gets overwritten by the default route to the sitemap.
