Magento 2.3 Warning: Declaration of MGS\Amp\Block\Html\Topmenu

Question

I am getting this error:

Warning: Declaration of MGS\Amp\Block\Html\Topmenu::_getHtml(Magento\Framework\Data\Tree\Node $menuTree, $childrenWrapClass, $limit, array $colBrakes = Array) should be compatible with Magento\Theme\Block\Html\Topmenu::_gethtml(Magento\Framework\Data\Tree\Node $menuTree, $childrenWrapClass, $limit, $colBrakes = Array) in /var/www/vhosts/fakedomain.com/httpdocs/app/code/MGS/Amp/Block/Html/Topmenu.php on line 105 

I get this error when trying to run the command - bin/magento setup:di:compile

I am trying to do this because even after I have the theme installed when i got to the home page i get an error. Those logs are saying:

Object DOMDocument should be created.";i:1;s:13313:"#0 /var/www/vhosts/fakedomain.com/httpdocs/vendor/magento/framework/View/Element/UiComponent/Config/Reader.php(95):

Any help would be appreciated in this.
