Can no longer edit text in PFD

@heather_8289 This suggests the problem might be related to a specific setting or a conflict on your system rather than a universal glitch. The dashed boxes you're seeing when you enter edit mode are bounding boxes that define the editable elements on the PDF, such as text blocks and images. They are a standard part of the editing interface. However, the problem is not that they appear, but that they are preventing you from editing.

Sometimes, an update can cause a corruption in the software. You can try to repair your Adobe Acrobat installation. In the application, go to Help > Repair Installation. This can fix corrupted files without a full reinstall. 

While it seems obvious, sometimes files with a .pdf extension are not true PDFs. If a file was created with a non-Adobe program or heavily compressed, it could behave unusually. One user reported that opening the file in Illustrator to edit and then saving it again as a PDF fixed their similar issue. Check if the PDF itself is protected. Right-click on the file and go to Properties. Look at the Security tab to see if there are any restrictions on editing. The document might have a password or security settings that prevent modifications.

If none of these solutions work, your best bet is to use the Adobe Creative Cloud Cleaner Tool and then performing a fresh re-installation is a very effective and often recommended step for resolving deep-seated software issues like the one you're experiencing. By using the Cleaner Tool, you are addressing the possibility that the problem isn't with the software's core files, but with a corrupted configuration file or setting that a normal uninstall would have missed.
