Bluehost Support: Thank you. After failed attempts on BH chat, I phoned support. They “escalated” the problem and then I received detailed instructions by email. Haven’t implemented them yet. Thanks.
OK. Thanks. I will try that again. I chatted with Bluehost support each of the last two days. Each time they said they would solve the problem. But nothing has changed.
Thanks, Takayuki. That was the help I needed. A little trial and error revealed that the “Adhesive” plugin was the culprit. I deleted it, and I also deleted “Sticky,” which has been deprecated. Everything is working fine now. Appreciate the prompt help!
