I'm using the latest version of WordPress, and all my plugins are updated.
When my site loads, it automatically redirects a user to other sites.
I viewed the page source from Firefox and it clearly shows that iframe is the culpret.
I've used my FTP program (FileZilla) to download the site to my machine and I used the Windows search functionality to look for anywhere that "iframe" text shows up in the files. It found dozens of files, and I looked through each of them, and I can't figure out what's causing the iframe redirect from my main page.
I was hoping someone would ake pity on me and try to help me determine where to look.
shown below is the only instance of iframe in the page source for the main page once it's loaded.
PLEASE someone help me! I'm driving myself nuts on this, and the site has been down for more than a day.
