Not Acceptable! Error notice

Hi,

I used this plugin to try and save myself some time but it has backfired on me.
I have some nestled buttons and I wanted to add one more so I do the following.

I used this for Find:

<div class="inline-button" style="display: inline-block;" align="center"><a href="https://icocryptoworld.com/etc/"><span class="coin-button" style="font-size: 14px;"><strong>ETC</strong></span></a></div>

And this for replace:

<div class="inline-button" style="display: inline-block;" align="center"><a href="https://icocryptoworld.com/etc/"><span class="coin-button" style="font-size: 14px;"><strong>ETC</strong></span></a></div>
<div class="inline-button" style="display: inline-block;" align="center"><a href="https://icocryptoworld.com/ngc/"><span class="coin-button" style="font-size: 14px;"><strong>NGC</strong></span></a></div>

But now when I click on the ETC button, it produces the following error.

Not Acceptable!
An appropriate representation of the requested resource could not be found on this server. This error was generated by Mod_Security.

How can I roll back the changes I can’t find how to undo what has happened, any help would be greatly appreciated.

Kindest Regards
Bam Bam
