How do I can fix this internal server error?

Every time I install those 3 plug ins, my website displays INTERNAL SERVER ERROR. Then, I tried to deactivate the APPOINTMENTS and activate the other two, those two worked fine. How can I fix this?

    The only plug in that is activated right now is the appointments+. These are the errors on the dashboard:
    Notice: Undefined index: QUERY_STRING in

    and when I activated the SUPPORT plug in, it doesn't direct me on my dashboard and shows me these:

    Notice: Undefined index: QUERY_STRING in /hermes/bosoraweb075/b2186/ipg.nakedorganixproducts/HaikuSalonandSpa.com/dev/wp-content/plugins/woocommerce-smart-coupons/woocommerce-smart-coupons.php on line 323 Notice: Undefined variable: newsletter in /hermes/bosoraweb075/b2186/ipg.nakedorganixproducts/HaikuSalonandSpa.com/dev/wp-content/plugins/newsletter/plugin.php on line 248 Notice: Trying to get property of non-object in /hermes/bosoraweb075/b2186/ipg.nakedorganixproducts/HaikuSalonandSpa.com/dev/wp-content/plugins/newsletter/plugin.php on line 248 Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate 4864 bytes) in /hermes/bosoraweb075/b2186/ipg.nakedorganixproducts/HaikuSalonandSpa.com/dev/wp-content/plugins/newsletter/includes/module.php(529) : eval()'d code on line 1

    but some of the errors show even though I didn't activate your plug in yet.
