Opencart 1.5 issue

Post by mcoates » Sun Dec 03, 2023 7:56 pm

Hi all,

Currently having issues with opencart with version 1.5.1. the issues are as below when logging into the admin area. Front end appears to be working fine.

[03-Dec-2023 11:43:35 UTC] PHP Fatal error: Uncaught Error: Call to a member function calculate() on null in /home/eulights/public_html/catalog/controller/module/bestseller.php:26
Stack trace:
#0 /home/eulights/public_html/vqmod/vqcache/vq2-system_engine_controller.php(44): ControllerModuleBestSeller->index(Array)
#1 /home/eulights/public_html/catalog/controller/common/column_left.php(72): Controller->getChild('module/bestsell...', Array)
#2 /home/eulights/public_html/vqmod/vqcache/vq2-system_engine_controller.php(44): ControllerCommonColumnLeft->index(Array)
#3 /home/eulights/public_html/vqmod/vqcache/vq2-system_engine_controller.php(55): Controller->getChild('common/column_l...')
#4 /home/eulights/public_html/catalog/controller/error/not_found.php(49): Controller->render()
#5 /home/eulights/public_html/vqmod/vqcache/vq2-system_engine_front.php(47): ControllerErrorNotFound->index()
#6 /home/eulights/public_html/vqmod/vqcache/vq2-system_engine_front.php(29): Front->execute('')
#7 /home/eulights/public_html/admin/index.php(164): Front->dispatch(Object(A in /home/eulights/public_html/catalog/controller/module/bestseller.php on line 26

When PHP errors are turned off the page viewed is the Error 500 page.

The website has recently been migrated to a new server and is now running on PHP 7.4 with the MYSQL updated to MYSQLI.

VQMOD has been updated to the latest version although this has made no difference to the errors shown

I have also seen other posts to clear the VQMOD cache files which has been done as well as server cache and browser cache.

All core files have also been refreshed with the OC 1.5 files to ensure they have no issues in there.

Malware scan has been done and found a few although they were in the Download directory looking like "images" and have been removed although the errors was the same before and after the removal.

More information can be provided if needed if it helps get this issue sorted :)

Thanks in advance :)

PHP 5.6 is depreciated. You need to use PHP 7.4 or preferably PHP 8. Ideally you need to upgrade to a newer version of Opencart or to buy yourself time upgrade to a version of Opencart 1.5 that runs on PHP 7.4.

I personally would use this:

https://github.com/IP-CAM/Opencart-v.1. ... stallation

Long term a newer version is your best option IMO.

That looks just like the same error, but your PHP 7.4 is configured to display more information about errors.

Try disabling you vQmods one by one.

I have done this via the database after searching how to do this as i dont have access to the admin area and has now produced another error

Code: Select all

Check both the PHP and OpenCart error logs for any other errors. Also check you're not missing any files.

I have just checked these and both are clear only historic errors from before upgrading DB to use mysqli from mysql

Did you check for any missing files by comparing your files on the server to a known working backup or a clean download?

ive not done this as their previous host does not make backups as its the customers responsibility to make them and the only backup they have is the dodgy version i have and the one before that was 2017 :-[

Personally I would clone your database and site files into /clone. Then upload 1.5.6.5 and run the upgrade script and see if your site comes back to life. Explore and test on the cloned version until you find a solution.

I tried to do this in the /clone as mentioned and got these errors after inputting the database information


Fatal error: Uncaught exception 'ErrorException' with message 'Error: Table 'oc_product_profile' already exists<br />Error No: 1050<br /> CREATE TABLE `oc_product_profile` ( `product_id` int(11) NOT NULL, `profile_id` int(11) NOT NULL, `customer_group_id` int(11) NOT NULL, PRIMARY KEY (`product_id`,`profile_id`,`customer_group_id`) ) ENGINE=MyISAM COLLATE=utf8_general_ci; ' in /home/eulights/public_html/clone/system/database/mysqli.php:41 Stack trace: #0 /home/eulights/public_html/clone/system/library/db.php(20): DBMySQLi->query('\nCREATE TABLE `...')

The username and password for the database was correct at the time and it was a fresh clean database.

Try uploading 1.5.6.5_rc in to the cloned site and run the install script which will upgrade the cloned database. Make sure you have adjusted the config.php and admin/config.php files in the clone folder to reflect the new folder location and cloned database. It's trial and error. There is no guaranteed solution.

Nope you can't disable vQmods via the database, they are xml files in the folder "vqmod/xml"

You can disable them by adding _ to the extension e.g. changing .xml to .xml_

so the update completed although then on the clone site it was the white screen for the front end and admin login page. when pressing f12 (inspect) there was no errors there.

I checked the php error log and nothing was reported, i checked the open cart and it said it cannot load a module to i commented this part out and the front end loaded fine although the admin area popped up with the PHP error of this one again....

Code: Select all

Fatal error: Call to a member function isLogged() on null in /home/eulights/public_html/clone/catalog/model/catalog/product.php on line 319

What did you comment out?

What is strange is that error is on the catalog part and not the admin.

Looking back at your posts, where the stack trace suggests your admin/index.php is trying to call a controller in the catalogue! Which is what is causing the errror.
#7 /home/eulights/public_html/admin/index.php(164): Front->dispatch(Object(A in /home/eulights/public_html/catalog/controller/module/bestseller.php on line 26
This just wouldn't be the case on a standard install of OpenCart.

As johnp suggested, you probably want to get someone to take a look fo you.

Double check your config.php and admin/config.php paths. Disable all vqmods via ftp. Clear your vqmod cache.

Feel free to PM me both config files and I'll take a look for you.

Hi,
It seems your $this->customer->isLogged() has some issue, calling on null. Please PM me the details to check on your website.
