Cache 404 option cause error on product save

[Germont]

Hi!
It's an Open Cart 3.0.2.0, with php 7.3
Suddenly the shop manager can save products only after many retries. This is shown on a white screen in admin side.
/admin/index.php?route=catalog/product/edit&user_token=Y7do5BwPTFh9eI3LkSp3WumvTT0lYANo&product_id=23261&filter_name=universal+amino
And this appears in error_log
[10-Dec-2021 16:25:56 UTC] PHP Fatal error: Uncaught Error: Call to a member function setPublicTTL() on null in /home/useraccount/public_html/catalog/controller/extension/module/lscache.php:284

This seems to be caused by Cache 404 pages. When option is disabled, error is gone.

create ticket here: https://store.litespeedtech.com/store/submitticket.php

it's fastest way to solve problem.

I think problem in installed vqmod subsytem. developers must solve this.

hi, please try disable the vqcache, it should be a conflict between lscache and vqcache.
