I left the "Max size of tracker item title in the search engine friendly URL" to the default 200 characters.
So we now have nice URLs for wishes, which will be a lot better for SEO. Ex.: https://dev.tiki.org/item2196-Tighter-integration-with-Apache-s-htaccess-error-messages
I noticed last word is chopped off. I have inquired to see if this is a feature or a bug
If text of tracker item is changed (which is to be expected), URL will still work, as with other SEFURLs (blog posts, etc.)
So this all works:
And Canonical URL is what it should be.
Thank you Ricardo Melo for having coded this recently. And thank you to Sylvie Greverend and Sébastien Lord-Jetté for the smart original SEFURL design on blog posts and articles.
