    Hi, 

    I'm trying to import LayerSlider templates to get started with. But it's giving me a internal server error. Following is a stack trace from the server logs.

    The wordpress site is running on a docker container with appsvc/wordpress-alpine-php:latest as the base image. In alpine versions of php, it seems GLOB_BRACE is not available. 

    Please see a similar issue reported on a different plugin. Compatibility with systems without GLOB_BRACE and PHP8 · Issue #6079 · osTicket/osTicket (github.com)

    Any help much appreciated.

    Kind regards,

    Hi Amila,

    Thank you for getting in touch with us. My name is John and I'm happy to assist you today. I appreciate your patience while we've been working towards your ticket.

    I'd like to thank you for the detailed bug report; it was very helpful. You're right, Alpine versions of PHP do not support the GLOB_BRACE flag. We'll investigate what we can do about it, and will release an update in the near future with a fix or workaround. 

    Thank you for letting us know about this issue, and I appreciate your patience while we try to find a solution to this issue.

    Best Regards,

    Hi John,

    Thank you for getting back to me.

    As a temp solution, I've removed GLOB_BRACE parameter from the code and so far it has not thrown any other errors. I was able to import templates after the change. I'm not a PHP developer myself, so not sure the importance of GLOB_BRACE. Please let me know when this is fixed.

    Kind regards,
    Amila

    Removing GLOB_BRACE can lead to unexpected issues with consecutive template imports since LayerSlider likely won't be able to remove the temporary files created by the import process. We're already preparing a patch for this issue that will be included in the upcoming update we plan to release early next week.

    Thank you again for letting us know about this issue, and I appreciate your patience.
