i am assisting a store owner on adding the sale/cost price module for their opencart store. 'OWC Product Sale and Cost Price' installed and enabled without any issue, but when attempting to access the module configuration, the following error is reported:



Notice: Trying to get property 'OwcBase' of non-object in /srv/stinger_prod/htdocs/store/system/library/owc/controller/owc_controller.php on line 23


from the apache error log:

Hi

It is working now, deleted vqmod\mods.cache file so it is now re-generated.

Keep in mind, I saw that you storage folder is outside the htdocs. Vqmod is not handling this good, so it can be that your vqmod\checked.cache file will be growing in size. When the size is big, the website will slow down. Or put the storage folder back into htdocs folder, you can use a different location then default, that is ok. Or sometimes clear both files checked.cache and mods.cache files.

Best regards
Dennis

Hi

Did you have installed vqmod https://github.com/vqmod/vqmod/releases/tag/v2.6.4-opencart ?

Hi

Vqmod is not running because of I think a unix owner issue. Check this url:
https://stage.stinger-performance.com/store/test.php with result OK,
and this url:
https://stage.stinger-performance.com/store/vqmod/test.php with error result.

When you have fixed it, enter url https://stage.stinger-performance.com/store/vqmod/install and check the cache folder in vqmod.

Best regards
Dennis

nah, not a ownership issue, it's because vqmod's .htaccess are written for apache 2.2 and not 2.4. Updated vqmod/.htaccess and vqmod/install/.htaccess. vqmod/install shows already installed.

odd thing now is stage is working, but prod is still throwing the class exception.

moved your ftp account up a dir so you can poke around stage and prod, and added an admin account on opencart for prod.

caches (opencart, vqmod) purged, modifications refreshed, no change in prod behaviour.

is it a non destructive operation to uninstall and reinstall the entire module?
