Thank you for reply.
I’m referring to WordPress Tag Cloud widget here https://codex.www.ads-software.com/images/b/ba/designwidget.png .
I updated to 2.0.63 and the problem is still there.
With “update the permalinks structure” I mean in Settings > Permalinks just click Save Changes. I am clearing the image cache, but it didn’t solve the issue.
The problem is not that much in the Tag Cloud, but in showing NextGEN pictures through URL https://www.somewebsite.com/ngg_tag/tagname/ with imagebrowser effect turned on.
When I click on some thumbnail I suppose it should show the picture in imagebrowser which means the URL should change to https://www.somewebsite.com/ngg_tag/tagname/nggallery/image/some-image/, but it changes to https://www.somewebsite.com/nggallery/image/some-image/ without the ngg_tag/tagname/.
I’m not sure I described the issue better.. but this topic https://www.ads-software.com/support/topic/plugin-nextgen-gallery-possible-tagsimagebrowser-bug?replies=3 is describing the same problem, maybe there it is better explained.
Thanks for any answer.
