Multiple Title Tags
AHREFs may throw a warning of "Multiple Title Tags".
This is may be a case of a dumb tool (ie. not context specific) being a dumb tool.
Title tags are allowed within certain contexts, such as with SVG icons. In the screenshot above, this is coming from the Simple Social Icons plugin
Note: we now recommend using the Feast Social Icons in the navigation menu per this tutorial.
There is absolutely nothing wrong with this, as long as you only have 1 <title> tag inside of you <head></head> tags.
