I purchased and installed the following template. Travelia for Joomla 4. I installed all the dependencies, including Sp Image Gallery, SP Page Builder Pro, SP Simple Portfolio and AcyMailing as well as the Helix components and plugins.
When I enable the theme as the default (Travelia) I get the folloowing error.
This is on the homepage of the website:
array_replace(): Argument #1 ($array) must be of type array, string given
When I go back to the default theme that came with joomla everything works fine again (Cassiopeia - Default)
