Duplicate column name 'slider_status'
Error
Duplicate column name 'slider_status' ALTER TABLE `[prefix]_nextend2_smartslider3_sliders` CHANGE `status` `slider_status` VARCHAR(50) NOT NULL DEFAULT 'published'
Cause
This issue happens, when you install the latest version of Smart Slider -> then downgrade it to a lower version -> update Smart Slider again to the latest version. Maybe some wrongly configured server cache can create this issue as well, in case you haven't done this process.
In the latest Smart Slider within the [prefix]_nextend2_smartslider3_sliders
database table we renamed the status
column to slider_status
. When you install an older Smart Slider version, that creates the status
column, when it doesn't exists. Then the latest Smart Slider would try to rename status
to slider_status
again, just it can't, because slider_status
already exists.
Solution
From your [prefix]_nextend2_smartslider3_sliders
database table, delete the status
column.
