Resolved Frontend White Screen after product Import

Hello Donna,

A blank screen means there is a fatal error, see the CSV Improved gives me a blank screen document for troubleshooting tips.

We will need to get the errors to show, then it will be clear what the problem is.

Hi Rolandd,

I've just had a message from support advising that CSVI has been spawning hundreds of files into my tmp folder (i was up to 12GB from 400mb), thus causing cloudlinux to throttle my bandwidth. I am still awaiting more information, and will test again later with the product/image import.

While i am awaiting additional information from my host, i just wanted to advise that i have all of the possible error reporting methods active (joomla, VM and display_errors = On, error_reporting = E_ALL and still nothing appears to be being logged. I am manually checking the php error log files under the log folder, as well as the server error logs in cpanel, but am not seeing any errors being logged after refreshing the page? Any additional ideas?

Best Regards
Donna

Hello Donna,

It sounds like you are using CSVI 6 or not? The tmp folder needs to be emptied first before you can continue. Perhaps wait with any new imports until we have figured out what exactly you are doing to prevent the tmp folder from filling up again.

Hi Rolandd,

The tmp folder has been emptied now. I have re-installed my site and imported some products and again i have a white screen 500 server error. I haven't added any image files yet to rule this out. Yes i am using CSVI 6, should i use 5.21.1 maybe? I have selected the delete file option in my template, but the file is not being removed from the tmp folder. I will keep you posted on what my host finds. Thank you for your support.
Best Regards

Hi Rolandd, the tmp folder is stable now, but still no luck with the imports. If i empty the VM tables the site comes back up. As soon as i try and import products i get the blank screen on the front end when i refresh. I have attached my import file, i am using 3 custom fields Size:, Power:, Materials:. I have also attached the debug log. I'm going to keep digging to see if i can see anything.

Thank you in advance
Donna

Hello Donna,

It is fine to use CSVI 6.

Do enable the error reporting in the Global configuration -> Server -> Error reporting and set it to maximum to see the error on the blank screen. Once we know the error, we know where to look.

The tmp folder is no longer being filled?

Rolandd, thank you for your continued support.

Error reporting is set maximum, as per your post, and has been from the onset. Aswell as being enabled in the php.ini. I ma baffled as to why i am not seeing any errors on the front end?

I am wondering if it is a problem with special characters as i have noted a few in my data. I have also lowered the records to be processed down to 100 per batch to allow me to monitor the import better. I receveived another 500 error in the admin panel and after refreshing the frontend managed to get some errors to show up:

Strict Standards: Only variables should be assigned by reference in /home/ladyloving/public_html/modules/mod_vm2_products/mod_vm2_products.php on line 316

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 86 bytes) in /home/ladyloving/public_html/administrator/components/com_virtuemart/models/product.php on line 790

So we have some progress. I have set the memory limit to 256M in the php.ini which still isnt enough? Do you have any suggestions?

Thank you for your continued support.

Hello Donna,

I am wondering if it is a problem with special characters as i have noted a few in my data.

That shouldn't be a problem if the file is UTF-8 encoded.

I ma baffled as to why i am not seeing any errors on the front end?

Perhaps some file in your system turns it off again. You can try the change mentioned in the CSV Improved gives me a blank screen document where you change the configuration.php file.

I have set the memory limit to 256M in the php.ini which still isnt enough? Do you have any suggestions?

So it is VirtueMart running out of memory, not CSVI. The only thing I can think of is increase the memory further until the page shows. This may be something you need to report to VirtueMart. I may depend on the number of child products as well. If you have a lot this will consume more memory as well.

Finally i'm getting somewhere, i have just had my host restart apache and have some errors being logged (i think i need a VPS, it would make troubleshooting alot easier). I have the following 5 errors appearing (multiple times).

PHP Strict Standards: Only variables should be assigned by reference in /home/####/public_html/modules/mod_vm2_products/mod_vm2_products.php on line 569, referer: http://www.####.co.uk/administrator/index.php?option=com_virtuemart&view=product
PHP Strict Standards: Only variables should be assigned by reference in /home/####/public_html/modules/mod_vm2_products/mod_vm2_products.php on line 316, referer: http://www.####.co.uk/administrator/index.php?option=com_virtuemart&view=product
PHP Notice: Trying to get property of non-object in /home/####/public_html/modules/mod_virtuemart_manufacturer/tmpl/default.php on line 81, referer: http://www.####.co.uk/administrator/index.php?option=com_virtuemart&view=product

File does not exist: /home/####/public_html/500.shtml, referer: http://www.####.co.uk/administrator/index.php?option=com_virtuemart&view=product

So i'm not as close to solving the issue as i would like, but i'm at least progressing and have something to work from. If you do have any additional suggestions please let me know, i will continue searching now i have this info.

In case anyone else has this problem, i have disabled the virtuemart Display all products module and the page loads. This is related to the /modules/mod_vm2_products/mod_vm2_products.php error and can be found under modules in the Joomla admin area.
