We regret to say that, but the standard Twitter search doesn’t work anymore. Twitter has banned all our accounts as well as some non-related ones and none of our claims worked. Twitter just doesn’t respond to our emails.
We provide an alternative version of Twitter search which parses Twitter’s HTML pages.
Also, we faced an issue we cannot authorize you with Twitter anymore. Please switch to Facebook or Google. If you have a paid subscription and would like to cancel it, you still can do it on the PayPal website.
