I don't understand why I take this message "Sorry, we are no longer accepting questions from this account. Although, I asked my last question at 22 August and I have contributed positively to the site. I read the Help Center.
First, read everything in the following page.
This will tell you what you can do to try to get out of a question ban. Note in particular that this is an automated system, and moderators do not create or remove this ban.
Since you've asked, you might benefit from knowing why your account has a question ban. You have asked a total of 29 questions. 13 of these questions have been deleted. An additional one question is closed. 23 of these questions have vote score 0 or less. This is a pretty poor record.
Both have poor titles that don't indicate the content of the question.
Using a more informative title would better attract people who might answer your question, and it will be easier for later visitors to the site to find this question to answer their own worries.
Both have misspelled words and atypical formatting.
Using correct spelling and grammar (if possible) makes it much more likely that others will bother reading the question. Many people don't read poorly formatted posts, as it's an immediate indicator that the asker hasn't put in much effort into the question.
Both questions are pretty vague.
I'm not sure what either of these last two questions are actually about. It's much better if each post is centered around a single, well-defined question. Initially it may be easier to really emphasize this single question. Providing some context and explaining what you've thought about concerning the problem can help indicate to others exactly what you're having trouble with, as well as help others know exactly what the question is.
Reading other well-received questions is a good idea to understand what sorts of questions are or are not well-received here.
