Uncaught Error: Call to undefined function….

Hi, I moved my website to another server. When I try to edit a page, this message shows up:

Fatal error: Uncaught Error: Call to undefined function Gutenberg_Templates\Inc\Traits\error_log()
in /home/users/yyy/www/wp-content/plugins/ultimate-addons-for-gutenberg/lib/gutenberg-templates/inc/traits/helper.php on line 29

Call stack:

1. Gutenberg_Templates\I\T\Helper::ast_block_templates_log()
   wp-content/plugins/ultimate-addons-for-gutenberg/lib/gutenberg-templates/inc/importer/sync-library.php:83
2. Gutenberg_Templates\I\I\Sync_Library::get_server_spectra_common_css()
   wp-content/plugins/ultimate-addons-for-gutenberg/lib/gutenberg-templates/inc/importer/plugin.php:906
3. Gutenberg_Templates\I\I\Plugin::template_assets()
   wp-includes/class-wp-hook.php:324
4. WP_Hook::apply_filters()
   wp-includes/class-wp-hook.php:348
5. WP_Hook::do_action()
   wp-includes/plugin.php:517
6. do_action()
   wp-admin/edit-form-blocks.php:272
7. require()
   wp-admin/post.php:187

The only option is to deactivate Spectra but I already built some pages with it so… what can I do to resolve this?
