Footer corrections

It is in your footer (php) that this code appears and created that monkey:

<a target="_blank" href="https://cyberchimps.com/">
<img alt="credit" src="https://onabih.ba/wp-content/themes/neuro/images/achimps.png"></a>

So I just delete this whole code that you wrote? Or just the links?

To delete the CyberChimps image and link to cyberchimps website, remove everything Krishna indicated beginning with <a ... and ending with ... /a>

This is how it looks in footer.php

Which part I should delete?

This part:

<a href="https://cyberchimps.com/">
 <img src="<?php echo get_template_directory_uri(); >/images/achimps.png" alt="credit" />
</a>

Thanks! That worked.

This part displays the CyberChimps image

<img src="<?php echo get_template_directory_uri(); ?>/images/achimps.png" alt="credit" />

Or you can remove the entire div used to hold the image:

<div class="row" >
    <div id="credit" class="twelve columns">
       <a href="https://cyberchimps.com/"><img src="<?php echo get_template_directory_uri(); >/images/achimps.png" alt="credit" /></a>
    </div>
</div>
