Sharing Cart plugin

<r><p>Hello,I would like to know if you are working on a version 5.1 of the Sharing Cart plugin that is compatible with Moodle 5.1.I have installed the currently available version in my Moodle 5.1 environment, but I am experiencing several errors during operation.Could you please let me know if there is an updated version in development, a temporary solution, or if there are plans to release one soon?Thank you very much for your help.Best regards.</p> <HR>---</HR> <H3><s>### </s>&#129302; الحل الهندسي المقترح:</H3> <p>Hello,</p> <p>Thank you for reaching out regarding the issues you're experiencing with the Sharing Cart plugin (block_sharing_cart) in your Moodle environment.</p> <p>First and foremost, it's crucial to clarify the Moodle version you are running. Moodle's standard release cycle does not currently include a "Moodle 5.1". The latest stable releases are within the Moodle 4.x series (e.g., Moodle 4.1, Moodle 4.2, Moodle 4.3). It is possible you might be referring to Moodle 4.1 (which has an end-of-life date of May 2024), Moodle 4.3 (the latest stable release as of late 2023), or perhaps a custom Moodle build.</p> <p>The compatibility of any Moodle plugin, including Sharing Cart, is directly tied to the specific Moodle major version it was developed for. Installing a plugin version not intended for your Moodle version is a common cause of errors.</p> <p>Below is a Standard Operating Procedure (SOP) to diagnose and resolve issues with the Sharing Cart plugin, taking into account potential versioning discrepancies and common troubleshooting practices as both a Moodle expert and Linux System Administrator.</p> <HR>---</HR> <p><STRONG><s>**</s>SOP Title:<e>**</e></STRONG> Troubleshooting and Resolving Sharing Cart Plugin Errors in Moodle</p> <p><STRONG><s>**</s>Problem Statement:<e>**</e></STRONG><br/> The user is experiencing errors with the Sharing Cart plugin (<C><s>`</s>block_sharing_cart<e>`</e></C>) after installing it in a Moodle environment they identify as "Moodle 5.1".
