Craft entries not saving We have received the Craft CMS and design files from our web developer with content already loaded into the Craft backend.

All of the frontend displays correctly but we are able to edit all the textual content in the 'Globals' sections and save it but when we edit any text/fields in the 'Entries' section and save the changes, the page reloads with the old content which hasn't been updated with the changes.

Does anyone know a fix for this?
Based on our comment thread, I would suggest to perform a manual update of Craft.

Download and unzip the latest copy of Craft, and replace the old app folder with the app folder that you just unzipped. No other files or folders need to be replaced.

Make sure to change the permissions of your new app folder, so you can perform auto-updates in the future.
