Thank you, Michael, I tried the first three solutions in the 404 FAQ entry, but they did not seem to work. Even if, let’s say, there is a conflict with some other slag called testimonial, I added some testimonials to the category Uncategorized, but they still do not show up http://saveourarchivalrecords.org/soar/category/Uncategorized/ On the other hand the link with Archives works http://saveourarchivalrecords.org/soar/testimonials-archive/
Any other ideas on what else should I try to make the category links and the direct link to testimonials work? Thank you very much!
