PayPal gateway (Test Endpoint failed)

[genpix]

I'm trying to configure PayPal gateway (1.0.5) in my store. There are not many options there to set (everything looks obvious).

When I press Test Endpoint button i receive Error message: Failed to connect to PayPal. More information can be found in the request log.

In the log, I see the following lines:

Today, 09:11

Request Sent - https://www.paypal.com/cgi-bin/webscr 0=null&1=1 Response received

What does that mean? What a "normal" log is supposed to look like?

also, when I try to place an order on my web-site (using test account), after choosing PayPal method of payment and pressing "Checkout" button I'm get redirected to "www.MYWEBSITE.com/index.php?_a=gateway" page, but the page is empty (probably because of the above error).

I also tried to configure PayPal Pro & Express Checkout plug-in (I selected "Express Checkout Only" option). Test Endpoint failed with exactly the same error (same log entry).

Is it my Web-Host server problem? What information I have to provide my Web-host tech support to seek help?

I just noticed that Currency "Fetch Rates" failed as well:

while similar request from 2 weeks ago worked fine (in the same log):

Are these errors related?

Update:

I went to my cPanel settings and just for giggles decided to reconfirm the PHP version settings. My account was configured to use PHP version 5.6, I went ahead and selected 5.6 again ant hit "change version".

After that, Paypal Test Endpoint started to work properly !!!

I have no idea why this stupid PHP version change (from 5.6 to 5.6) worked. I compared new .php.ini with my old back-uo. Files are identical!

Anyway: now my side is kinda working. But ....

I can not do a check-out using Firefox ( .../index.php?_a=gateway  is an empty page, and there is no any redirections). Surprisingly, Google Chrome works just fine, this page gets redirected to PayPal web-site. Have not checked IE yet (I don't have it installed).

What can cause Firefox to stuck on  an empty page .../index.php?_a=gateway (after hitting "Checkout" button)?

I just tried to place an order as a guest (without creating an account on my web-site), and I was redirected to PayPal web-site after clicking on "Checkout" button. It is a problem only if I create an account first and then try to do a checkout, then I see an empty page.

any ideas why this is happening?

The "re-installation" of PHP 5.6 is a weird one - no doubt.

For CubeCart's Request functions, it uses cURL, a PHP add-on functionality, to make communications with outside web sites. Maybe your host had this switched off, and "re-installing" PHP switched it back on again.

Please create an error_log and examine its contents when you next get a blank page.
