I have a situation where event espresso form buttons are working sometimes on first click and then page refreshes and then the form submit buttons are then turned into adclick add links which go to random websites. Have you heard of this or know whats happening? Thank you

Hi there,

I had a look over your site and in short, it looks like your site has been compromised.

There is a secure.js file being loaded from another site which is adding an iframe to the page and running a .PHP file from within your site. That’s not normal behaviour and it is likely what is causing the above. The iFrame moves in and out of focus as the pointer interacts with elements on your site, basically, it’s a hidden element that ‘moves’ in the way when you click.

With a little CSS tweaking this is what I see:

The red arrow on the top left is where my most was (doesn’t show on my screenshots) and as I move the mouse around that box/element follows waiting for me to click it.

You can spot this on the EE form submissions because that is where you are trying to interact with the site but it’s the iFrame causing the problem.

Your host may provide an option to ‘clean’ your site when infected, or you could try the folks at Securi.

Thank you very much. Turns out all I needed to do was update the theme. I also took more recommended security steps as in updating all plugins and deleting unused themes/plugins.Thanks again.

Just to note, if the theme is where the files were present then updating it would have replaced the entire theme so would have removed those but may not have fixed whatever vulnerability allowed for this (although at the same time may well have done).

Basically, just be vigilant and keep an eye on the site to confirm it doesn’t happen again. If whatever vulnerability caused it is still there you will likely run into this (or something similar) again.

Agreed! Thanks for the tip.
