Missing "Paypal Express Checkout" module after installation

[n0odle96]

Good day zen-cart masters!

After fresh install of zencart in public server, Paypal Express Checkout module is missing in the Modules->Payment page of the Admin section and there is no edit options which supposed to be displayed in the right side for each item selected. I also tried installing it to my local machine but there is no problem with that.

Could someone please help me on this because my shopping site will soon be launched in public so I needed to check the process of payment using Paypal express checkout method.

Reupload the files from the distribution.

Thank you for your reply Kim.

Installation file used was from the distribution, no files were modified yet.

Your FTP program has missed or currupted one or more of the files needed - re-upload ALL of the files.

I uploaded the installer file in zip format to make sure I will not miss anything upon uploading then extracted it using putty.

Anyway, I'll double check the uploaded files. thanks!

... and there is no edit options which supposed to be displayed in the right side for each item selected.

Both of those symptoms are a direct result of a PHP error occurring when the system is trying to initialize the details for the next (undisplayed) payment module in the list.

So, as Kim mentioned, re-uploading the original files would normally aid in resolving files that didn't get transferred to the server correctly the first time.
Either that, or you've attempted to add another payment module but done it incompletely, or tried to physically remove one but done so incompletely.

You may need to use a debug logging tool to properly identify the PHP errors you're getting as a result of whatever is unique to your situation.

The debug logging tool mentioned in step 2a of this FAQ can be applied to the admin side and/or the catalog side as necessary: https://www.zen-cart.com/tutorials/index.php?article=82

Hi Dr. Byte! I installed the debug function as you mentioned and found out the error.

[18-Dec-2008 18:21:08] PHP Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 92160 bytes) in /var/www/html/myShop/includes/modules/payment/paypalwpp.php on line 1691

Line 1691 refers to a blank line and the next line is this
$this->zcLog('ec-step1-addr_check3', 'address details from override check:'.print_r($address_arr, true));

Is there anything I need to configure to make this work?? I already checked the files in the server and compared it
to my local copy and found none were missing.

Thanks in advance.

That message means the maximum memory limit setting in your PHP configuration which sets the maximum amount of RAM per connection ... is too low.

Work with your hosting company to increase that setting.

OK, I will coordinate this problem tomorrow to our administrator and will inform you about the result.. Thanks again doctor byte!!

Hi Dr. Byte, maximum memory limit was adjusted by the administrator and the item I'm looking for is now available and can be configured.

Arigatou sensei!!
