In a Magento 1.9 installation we had just the problem, that it was not possible to make any change in the payment. No matter what we wanted to change after trying to save always came the error message "Wrong field specified.". It did not matter, if you wanted to change the name of a payment method or wanted to activate or deactivate a payment method.
Through some research it was clear soon, that the problem seems to be related with the extension "PayPal Plus" of iways. A general problem but it is probably not, as in other installations with the same version of the extension (1.9.2) there is no problem here. Furthermore, it seems to have to do with the integration of third-party payment methods, because the following adaptation solved the problem:
In der app/code/community/Iways/PayPalPlus/Block/Adminhtml/System/Config/Thirdpartyinfo.php die Zeile 126 comment out and replace with the following here.
'payment_third_party_modul_info_text_' . $paymentModel->getCode(), So it should look like.
$field = $fieldset->addField(
// $paymentModel->getCode(),
'payment_third_party_modul_info_text_' . $paymentModel->getCode(),
'text',With this adjustment, the error during installation then no longer showed up and you could save back to normal.
Good day,
I have this problem also in a recent Magento 1.9.4.3 Installation. PayPal Plus also does not appear as payment method in the frontend. The fix itself brings no improvement, and the error message still. caches etc.. were emptied.
Hallo,
I feel like Daniel, I tried the fix, but does not work. Run on too 1.9.4.3 and today I tried to include paydirekt in my PayPal Plus Checkout. Now I can’t save anything. Super strange…
At 1.9.4.3 we have not made any adjustments so far. to have to do, therefore I can’t say anything more about it at the moment.
If the line with “return $field->toHtml();” is commented out. At least the whole thing can be saved again.
Thx, it works on 1.9.4.5 with this Step.
