(English Version) - Adobe Photoshop CC: XML Parsing Error: not well formed - How to solve

Hello!

After a long time I will post this help for those who have Adobe Photoshop installed and are receiving an error message after finishing the program:

XML Parsing Error: 'no well formed (invalid token) at line 1 of config.xml'

This happened to me in the latest versions of Photoshop (until 2020), and only after installing the Google NikSoftware Colection plugins. (Nik Plugins).
It happened using both Windows 10 and Windows 8.1 (both Pro version).

Here is the solution, for Windows:

Open the Windows Run (Window key + R) and copy and paste this line:
%LocalAppData%\Google\Color Efex Pro 4
Then hit enter.
Look for the "Favorites" folder and delete it.

Ready. It is already functioning normally. In this case, closing normally. Haha

If you use other versions of the Nik suite and it is showing this problem, just open the %LocalAppData% folder and look for the Nik instalation folder or Color Efex Pro and delete the "Favorites" folder in it.

For Mac, it should be something similar. Search for the Nik configuration folder for your user, and delete de "Favorites" folder under Color Efex Pro folder.


Hugs, and good photos and edits.
