I can’t get rid of the “Categories” and “Archives” tabs from my menu bar. I have no plug-ins. I have tried adding and deleting them as widgets, to no avail. I have moved the widgets to “inactive” – didn’t work. I tried to edit the code under “header,” “theme,” etc. but these two tab items don’t seem to appear anywhere! Any ideas?
You are using a very outdated theme which in all likelihood is not going to work well with your version of WP.
This theme hasn’t been updated in over 2 years. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.
