[Resolved] Gravity Forms Multilingual 1.8.0 Internal Server Error

This thread is resolved. Here is a description of the problem and solution.

Problem:
If you're experiencing a 500 internal server error when clicking the "Original anzeigen" link in WPML > Translation Management > Aufträge, and the URL appears malformed like this: 

https://www.studium.uni-mainz.de/wp-admin/%3Ca%20href=%22https://www.studium.uni-mainz.de/?gf_page=preview&id=1%22%20target=%22_blank%22%3E%3C/a%3E

, it's likely due to an issue with HTML hyperlink formatting in the URL after upgrading to Gravity Forms Multilingual 1.8.0.
Solution:
We recommend modifying the code in your Gravity Forms Multilingual plugin. Specifically, you should edit the file located at 

.../wp-content/plugins/gravityforms-multilingual/inc/gravity-forms-multilingual.class.php

.
Find the line 267 and replace:

$post_view_link = sprintf( '<a href="%s" target="_blank">%s</a>', get_home_url() . '/?gf_page=preview&id=' . $form_id, $label );

with:

$post_view_link = get_home_url() . '/?gf_page=preview&id=' . $form_id;

This change should correct the URL and resolve the error.

Background of the issue:
I am trying to click on the link "Original anzeigen" in WPML > Translation Management > Aufträge (may be Jobs? compare in the screenshot attached) in the title column. The link leads to a 500 internal server error due to a HTML hyperlink in the URL, like this: hidden link. If you correct the URL to hidden link, it works just fine. This happens after an upgrade from Gravity Forms Multilingual to 1.8.0. For your information: hidden link is the primary address of a WordPress Subsite in the Multisite cms.zdv.uni-mainz.de.

Symptoms:
I get a 500 internal server error due to a malformed HTML hyperlink in the URL. The Apache error log shows: 'Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.'

Questions:
Why does the link in WPML > Translation Management > Aufträge lead to a 500 internal server error?
How can I fix the malformed HTML hyperlink in the URL after upgrading to Gravity Forms Multilingual 1.8.0?

To answer Shekhar Bhandaris Question: "So if you don\'t click the view original error the internal server error doesn\'t occur right>?"

Yes, that is right.

Hello there,

Our compatibility team suggested the following workarround:
- Edit .../wp-content/plugins/gravityforms-multilingual/inc/gravity-forms-multilingual.class.php file.

Look for line 267.

Change this line:

$post_view_link = sprintf( '<a href="%s" target="_blank">%s</a>', get_home_url() . '/?gf_page=preview&id=' . $form_id, $label );

For:

$post_view_link =  get_home_url() . '/?gf_page=preview&id=' . $form_id;

Let me know if this helps.

Thanks

This will be fixed in the next release, I assume?
