I have a Sharepoint Portal with "Sharepoint Server Publishing" feature activated at site collection level. I have few pages in subsite and some page have "Page" and "publish" tabs and for some pages I only get Site Actions menu. Any suggestions?
Normally, pages created in site/SitePages wont have the Publishing tab because versioning on these Library types are set to "Create major versions" . Major versions do not require Publishing as it creates a new major version when you check-in, save.
Pages created in site/Pages will have the publishing because that Library type is set to create "major and minor (draft) versions".
Anyways, to fix the issue for pages/items created in SitePages, go to the Library Settings > Versioning Settings > Select "Create major and minor(draft) versions.
Go back to any page in that library and you'll now find the Publishing tab.
