One-Page Checkout [Support Thread]

[lat9]

I did some further tests. Here is what I found:

Before the upgrade to 2.6.0, my site can be displayed as normal under my browser (chrome). I leave the browser tab open. After I upload all those files, my admin page can be displayed as normal, but my site (same tab) will show white screen (HTTP 500). Even I open a new browser tab, it will still show the white screen. Then I open an Incognito tab and visit my site, it can be displayed as normal with no log generated. If I open a different browser (like Firefox), I can open my site as normal.

After I downgrade my plug-in back to 2.5.5, my white screen tab can display my site as normal. This issue can be reproduced in a different computer under my network.

I have no ideas. Not sure if it is related to my browser's cookie or cache?

HTTP 500 indicates a PHP fatal error of some sort. Check the site's /logs directory and post the contents of a generated error log.
