Testing is not a valid entry
This seemingly innocuous error might be indicative of a much deeper issue, either with the operating system or the program itself. Some programs have a list of reserved names, which cannot be used for anything else. It is possible that "Testing" is one of those words, although it is unlikely. Unless a list of these reserved words exists in the manual, it is impossible to know in advance whether or not a title is valid until you try it.
To try to troubleshoot this problem, do the following:
1. Try to remove one letter from the word "Testing", meaning try to input "Testin", "Testi", "Test" and so on. Note when the program allows you to post the title and when it doesn't.
2. If no title is allowed, try putting another word, such as "Program", and repeat the procedure from step 1.
