Plesk Apache error config files

Hi, we are experiencing apache issue we are not able to resolve with the pleas repair cli commands.

New configuration files for the Apache web server were not created due to the errors in configuration templates: apache2_ls_bak: Syntax error on line 146 of /etc/apache2/apache2.conf: Syntax error on line 2 of /etc/apache2/mods-enabled/mpm_event.load: Cannot load /usr/lib/apache2/modules/mod_mpm_event.so into server:

We need experienced dev for quick fix.

Thanks
