after upgrading to latest version of Sydney Pro, the tab Category is no longer showing up when trying to add a new Service
hmm try going to your “Types” tab on the lefthand side with all the other things…(post media pages etc)
then click “Taxonomies” you should see Categories and Tags. Make sure Categories is active and see what is listed on the “Post type” if you dont see Services under Post Types click Edit under Categories(might have to hover mouse around) Once you go there you will see “Post Types to be used with this Taxonomy” then check box the ones you want (Services) then click Save Taxonomy…then you should have Categories under services…
Please refer here.
the flags was already checked, but as soon as I saved all come back
