ads.txt file content extension duplicates entries #5
Description
In case plugin v1.9.4 is installed/activated and the root directory already hosts an ads.txt, the content is extended at the end of the file.
Problem:
a) it is not checked, if the added content already exists in the given file which potentially leads to double entries in the file
b) a comment "# Ver. 1.9.1" is added, still refering to an old plugin version. Maybe the versioning comment should be removed completly or correctly upgraded with each release
