Hi , I'm trying to test a website in xampp using Zen cart 157 . Everything seemed to work fine until I install some language packs ..I get a blank page login as administrator unless language is set to english . Tried with Edge, Firefox to no avail.The only way to resume is to restore from a backup. Any help would be greatly appreciated..Thank you
best regards,

guits Thanks for giving me access to this site

When blank pages or partial blank pages occur, generally there is also an error message logged in the logs directory. Because it appears to be an admin related issue, would expect to find a file matching the initial pattern: myDebug-adm-. Thing is, you're welcome to post the general content of that most recent file, but please remember that the admin file will contain the admin directory in it. The admin directory name should be obscured if/when posting. And to that, when posting, please click the # button in the messagebox toolbar just before pasting the code.

You mean you installed more than one at the same time.

And of those language packs, which were marked as tested with ZC157?

As far as I can see only the Indonesion is in the plugins. Others may be elsewhere: spanish is in my Github (and not in plugins as I have no feedback, and have not upgraded my own site yet, but it's tested with vanilla ZC157).

There is no management of the language packs so caveat emptor.

MC has already indcated the solution.
