Hi there, I have a client with an old site with lots of links to non-secure images from other sites and it is throwing a mixed content security warning in some browswers. How would I use DB Replace to convert something like:
img src="http:// <<< to >>> img src="https://
So that the insecure link becomes secure.
Im sure it can be done, but Im very nervous about making a mistake that will harm the site. I have the site backed up in case I need to revert.

Thanks in advance for your help, I sincerely appreciate it!
