If you do not have any server logs, are you able to go into tools > Import WP > Settings / Tools Tab > Enable Debug Mode.

Then the next time you run the importer (manual or via cron) it will write a log, which can be viewed from the Importers > Edit importer screen, at the bottom of the page there should be a "Show debug" link at the bottom right, click this to open up a debug panel, and right click and save as the download link next to import logs, and attach to this ticket.

This might allow us to understand what is going on with your server.

Sure , there is

Can you send a copy of your WordPress site health?

Hi James , record is around 4000 lines ;

Cron was setup to use the task sheduler , i could isee in your plugin 'next import in 800s' ..

Unfortunately i dont have logs

I tryed  manually and it crashed again

Yes I have cloudflare dns , my server is a cyberpanel vps

Hi,

That does not sound good with your hosting timing out.

The plugin has been built to have low cpu and memory usage so these should not be an issue, Out of curiosity how big/number or records does the file have you are importing?

Can you confirm if your cron was setup to use the task scheduler, or was it using the default wordpress cron that runs when a page is loaded ?

Are there any error logs on your server?

When you tried to run the import again was it via manually running it?

the 542 error suggests that you have cloudflare running infront of your server, and it could not handle the connection / timeout, is your server a vps or shared hosting server?

Hello , bad news this morning
During import , the website became unaccessible for hours . this morning i had to restart manually the vps from the host.
After checking logs , cpu never go over 50%,
I tryed to run import again , all goes well until 524 timeout error , and then nothing , have to restart hole server
I loose a night of traffic
I have to distable the plugin

If you have your wordpress cron setup to run via a task scheduler then it should be no issue: https://developer.wordpress.org/plugins/cron/hooking-wp-cron-into-the-system-task-scheduler/

Thanks , all working now .

One other product with same sku was in trash can, deleting it solve the issue.
Are you positive that every hour , the plugin will fetch the a new csv , not always using the same ?( i set up for every hour )

Thanks again

Hi Charles,

2.jpg this suggests that you have two products that share the same sku which is not allowed in woocommerce and why the importer has failed, if you can look at both products and see which one has the wrong sku and update it to be correct, then when the importer is next run this error should not appear.

Hello James , thanks for your support

I did as you said and I have an error with sku , 
Seems like "ID" is used (nomber woocommerce create when you add a new item ) instead of "UGS" ( barecode i add manually )

Hi Charles,

Just to keep everything together:

Copying from the email chain, for future reference about the timeout issue, it is solved changing default wordpress curl timeout by adding the following snippet to your theme:

https://pastebin.com/qqdBXYBw 

Also in your last email you sent along with the 2 attached files:

the snipped worked but i can’t get the plugin to work .
Usecase : update stock from csv
Please see files attached.

Based on what i can see in your screenshots it looks like you are trying to update a stock for woocommerce products, is this correct?

If you are, can you please install the https://www.importwp.com/integrations/import-export-woocommerce-plugin/ addon.

New Importer

Once installed you need to create a new importer and select the WooCommerce products template on the new importer screen.

Edit Fields

This will then add extra woocommerce fields, where you can set the stock and sku fields, under the inventory section, enabling the stock fields via the "Enable fields" button.

Setting the managed stock field to "yes" , stock quantity field to your {7} value

Permissions Step

Disable create and remove permissions, enabling update permission, setting the import to only the following fields. and setting the fields text area value to

_manage_stock
_stock

With all these set, limit the importer to 1 record and test if the import succeeded.
