Hello,

Thanks for reaching out to us. Could you please share temporary administrator access to your Joomla backend? You can provide the credentials securely in the hidden content section. Also, please take a full backup of your site before we make any changes.

Once I have access, I’ll investigate further and see what’s causing the issue. Let me know once you’ve shared the details!

Best regards,

Sure

I have update this line on this path

administrator/components/com_speventum/views/sessions/tmpl/default.php line no 127

administrator/components/com_speventum/views/schedules/tmpl/default.php line no 123

and here

administrator/components/com_speventum/views/speakers/tmpl/default.php line no 125

this code

<tr class="row<?php echo $i % 2; ?>" sortable-group-id="1">`

replaced with this

<tr class="row<?php echo $i % 2; ?>" <?php echo SpeventumHelper::getVersion() < 4 ? 'sortable-group-id="1"' : 'data-draggable-group="1"';?>>

Now, You can sort speakers, schedules and sessions form backend by drag and drop.

Thanks

thank you so so so Much.
