bootstrap.php file missing

hi all!

Firstly, I know nothing about WordPress and don’t even know what version is running.

I DO have a lot of IT experience, working in the industry for 20+ years… and I have taken on a new role in a smaller company which has a WordPress website that broke in the past few days without any updates being done to it.

The company uses the Paeon engine/plugin. The website now just displays the following error messages:

Warning: require_once(/home/clayfiel/public_html/wp-content/themes/paeon/engine/bootstrap.php): failed to open stream: No such file or directory in /home/clayfiel/public_html/wp-content/themes/paeon/functions.php on line 22

Fatal error: require_once(): Failed opening required ‘/home/clayfiel/public_html/wp-content/themes/paeon/engine/bootstrap.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/clayfiel/public_html/wp-content/themes/paeon/functions.php on line 22

I can’t get into the wp-admin page either – same error.

I can however get into the FTP site for the site.

I can confirm that the bootstrap.php file is nowhere to be found in the path above…

Please advise as to what I can do?

Many thanks in advance!

Ross.
