[SOLVED] Hipay module issues

[MangoPolo]

I have modified a little the module to make it process payments for my local country currency by being converted into Euro , because Hipay does not support my currency. Anyway, this is not the most important information.
The issue comes from another side. 
I needed to change in Prestashop currency settings the order between USD and EUR . Change places. To make EUR be first and USD second, so I deleted USD and then creayed again to make it take the last position. SO after this, in Hipay settings, I already had 2 boxes with USD. Which is not good. I uninstalled Hipay module, and installed it again. But all the settings have been kept. Then I went to PhpMyAdmin and deleted all rows with _HIPAY . This did the trick partially. All account settings were gone, but anyway there remained 2 boxes of USD . And also, another problem occured. Now Hipay is not anymore showed in the checkout page as a payment method.
How do you think? This is module caused problem or prestashop? I cleaned cache. I even disabled Cache. Nothing helps. 
Hipay module sees two existing USD currencies ( duplicated ) because if I enter USD account info in the USD box, both boxes become filled after Save.

Where should I dig to remove this issue?

 

Edit:

I found the duplicated row in ps_currency and removed it. Deleted again the HIPAY rows in ps_configuration and now the module seems to see only 3 currencies as it should. 
But the problem with the payment method Hipay not showing up in the checkout page is still there. What could've I deleted so that the method not to show up ?  In active payments it is showed. In the QuickCheout  module is showed. Only on the checkout page it isnt.. Could it be because I have also deleted not only rows starting with HIPAY_ but also including HIPAY in the middle ( CONFIG_HIPAY....etc )  ?
I have a feeling that most of the changes made in the BO they do not affect the php database. How may I understand if it so or not? Why should I delete everything manually from the database?


Prestashop 1.6.1.5 ( Updated from 1.6.1.4 ) by 1Click Upgrade module.

 

 

Edit:

SOLVED. It is because of a bad hosting company I USE. PHP WRITING IS SOMETIMES INTERRUPTED.

MARKED A SOLVED.
