getting codenames as titles

Hi Naresh,

Please check if resource files for default culture (if you didn't changed that, it should be something like 'CMS.resx') exist in CMS\CMSResources on file system. If does not exist, you can find localization packs on this link, or copy this files from clean Kentico instalation.

Best regards, Dragoljub

These are localisation string keys. You've selected a lanugae for your UI that isn't supported or that you don't have a translation pack for. Check your web.config file for a key setting similar to the following:

<add key="CMSDefaultUICulture" value="en-ie" />

If you have that, try changin it to en-US until you can get a localization pack. There are some tips for this here: Setting the default UI culture. If it's just your user experinecing the issue, try looking at Applying a culture to a specific user's UI

If you recently upgraded you may need to resign your macros. I've seen this before with upgrades as well as with what Matt mentioned too.
