How do I reset default settings

I have the same problem. The Booster pack removed ajax and the script below dissapeared completely. This is not the only change. I need to restore the default wp settings.
Any idea how?

<script type=’text/javascript’ src=’https://[&#8230;..]/wp-includes/js/wp-ajax-response.min.js?ver=3.9.2′></script>

@alan M. Donaghey and @luxcav,

Most likely it is your cache plugin. If you are using a cache plugin you may need to clear or disable your cache after saving plugin options.

Speed Booster Pack plugin does not affect the database, all plugin settings becoming null after deactivation.

To disable all plugin options simply uncheck all options and empty all fields then save the changes.

Dear Tiguan,
In most cases you are right, but in my case I hadn’t a caching plugin. Instead I found a virus inside my jquery.js file.

Somehow my js includes inside wordpress was hacked, exactly after I installed Speed Booster Pack. I cannot imagine how this happened.

What a story!

I understand that you think SBP is at fault for this?
What virus is it? How’s it called? How did you found it? What proof do you have before blaming this plugin?

Hello Tiguan! I don’t blame your plugin for it!!!

Exactly after writing my previous message, yesterday, i found my site infected by a virus that leaves a “Free Software Foundation” trace in my js files.

I don’t believe your plugin is responsible, instead your plugin helped me find the infection.

I cannot find anything about “Free Software Foundation” virus though in the web. Does anyone know something about that?

The “Free Software Foundation” is not a virus.

It is a snippet from GPL2 license information used by WordPress that most plugin use it. Here’s a sample.

Perhaps this snippet appeared somehow in your page source or in front end, due to a php error belonging to your theme or other plugin or improper configuration of them.
