Promokit Helpdesk Alysum

Hi.

Currently using warehouse theme but purchased Alysum to use instead.

After adding Alysum and then choosing to activate I got errors linked to an IQIT compare module. Really unsure why simply choosing to activate Alysum would cause an IQIT error.
I deleted Alysum and yet my module manager link from back office now produces an error

Attempted to load class “Cache” from namespace “Promokit\Module\Pkthemesettings\Cache”. Did you forget a “use” statement for e.g. “Sensio\Bundle\FrameworkExtraBundle\Configuration\Cache”, “Doctrine\ORM\Cache”, “Doctrine\ORM\Mapping\Cache”, “Doctrine\Common\Cache\Cache” or “PhpCsFixer\Cache\Cache”?

[Symfony\Component\Debug\Exception\ClassNotFoundException 0]

I then deleted both Alysum AND Warehouse themes and re-installed Alysum to get the error

An exception occurred while executing ‘SELECT t0.id_tab AS id_tab_1, t0.id_parent AS id_parent_2, t0.position AS position_3, t0.module AS module_4, t0.class_name AS class_name_5, t0.route_name AS route_name_6, t0.active AS active_7, t0.enabled AS enabled_8, t0.hide_host_mode AS hide_host_mode_9, t0.icon AS icon_10 FROM pslh_tab t0 WHERE t0.module = ?’ with params [”iqitadditionaltabs”]: SQLSTATE[42S22]: Column not found: 1054 Unknown column ‘t0.route_name’ in ‘field list’

[Doctrine\DBAL\Exception\InvalidFieldNameException 0]

So again deleted Alysum and reinstalled Warehouse.

Pretty stuck to be honest as cannot even get Alysum to be active to set anything up even as a brand new clean install with no other themes installed.

Any help would be appreciated.
