According to support, UpdraftPlus Premium modifies the version number of the installed plugin to reflect the activated addons.
Example: The plugin that you can download from your account has version number 2.25.4, but when you install it, this becomes version number 2.25.4.26.
As a consequence, the WP Cerber integrity checker will not accept the original plugin when you upload it to compare the original files with the installed files, since WP Cerber detects a version mismatch.
Here is how you can solve the problem easily:
- Read the current version number in the WP backend (e.g. 2.25.4.26).
- Make sure you have the original ZIP file of the same version, excluding the last number (e.g. 2.25.4).
- From that ZIP file, copy the file updraftplus.php. In that copied file, adapt the version number which you will find in the first few lines of code.
- Copy the modified file updraftplus.php back to your ZIP file.
- Upload this modified ZIP file to the WP Cerber Integrity Checker.
