Q&A for How to Edit a Facebook Business Page

Go to Settings on your page. Find Restrictions. Click on that and you can choose.

Go to Page -- on the left side just below your page profile picture you will be able to see the tabs Home, About, Shop, Photos, etc. Click on Manage Tabs. Now, on the right side toward the bottom of the page, ensure that the 'Review' option is set to visible. If you do not see a review option at all, then click on Add Tab and do what's needed.

Go to the photos page and select the photo you want to edit. Then, hit the "Edit" button. To add more photos, go to the photos page and click "Add Photos." To delete a photo, select the photo you want to delete and click "Delete."

Try editing in a different browser. If you are doing it in Chrome, for example, try Firefox or Internet Explorer. If you have tried all of the browsers, try it on a different device. Your local library probably has several computers that they'd let you use.
