Yesterday, or perhaps the day before -- I can't remember now -- I discovered that the URL link button on WP's post page is no longer working. In other words, if I select text in a post that I am composing, and then click on the URL link button, nothing is happening. The little window is no longer appearing on my screen where I enter the actual URL. The only way that I can add a link at this current time is if I switch from the "Visual" tab to the "HTML" tab and then manually add the HTML code for the link.
Other than updating "Xcloner-backup-and-restore" four days ago, installing SEO Smart Links Premium Personal version the day before that are the only changes that I have made to my WP setup this past week.
I honestly don't see how Xcloner could affect the URL link button, being as it is in no way related to it, and I don't even run Xcloner everyday. On the other hand, there would seem to be a more direct relationship between the URL link button and SEO Smart Links.
BTW, I deactivated both Xcloner and SEO Smart Links one at a time, and the problem still persists.
Has anyone else experienced this anomaly? If so, how did you resolve it?
I have posted a similar message on the SEO Smart Links support forum.
