Can Not Save The Changes Or No Save Button

Does the settings page end with the GTIN field? Since that field brings in content from all your postmeta in use on your WordPress installation, something in there might have a special character that’s breaking it.

If that sounds like the case, press Ctrl+U to view the source of the plugin settings page and then scroll all the way down to the bottom and take a screenshot and send it.

That might tell me what special character needs to be escaped.

Hi I’m having exactly the same problem. all my product GTIN fields in Woo are empty and i can’t find the problem
Could you have a look?

Many thanks

Thank you for sharing this screenshot. Could you please check your PHP error log to see if there are any error coming from this plugin on your server?

Hi Nate
i have checked, the only errors logged are coming from an aksimet anti-spam plugin
thank you
Janet

Interesting. While analyzing that section of code, I couldn’t think of any compatibility issue with that except for the nearly impossible case where you don’t have any postmeta existing in your database for products or variations. So, I just released a bugfix update that checks the results to make sure it’s an array and not empty before it runs a foreach() on it.

However, I doubt that will fix your issue because normally trying a foreach() on a non-array will produce an error in your PHP error log.

But, give it a try just in case. Version 2.6.3.

Any other ideas you have for me? Anything special or different about your WordPress setup? What PHP version are you using?

Hi Nate
not anything particularly odd as far as I know. Php is 5.6.36
Wordpress 4.9.7–en_GB
Woocommerce 3.4.4
X theme by Themeco running a child theme ver. 6.2.5

As far as I know all pretty standard

Did you update plugin yesterday? Did that help or no?

i did update the plugin yes. No change there. I have attached a screenshot of the plugin settings screen. I’m not missing something really obvious am i?

PHP is definitely hitting an error in the area where it’s querying the database for all the post meta keys.

You said you checked the error log, but did you check if you have an error log file inside your wp-admin folder? Sometimes there’s a separate error log there for just the admin side.

good point. just checked and i got:
[31-Jul-2018 07:39:36 UTC] PHP Fatal error: Call to undefined function mb_strimwidth() in /home/propress/public_html/wp-content/plugins/ecr-google-customer-reviews/ecr-google-customer-reviews.php on line 202

Ah ha! There it is. Why wouldn’t your server have this standard PHP function? https://php.net/manual/en/function.mb-strimwidth.php

I’ll replace it with something else and release an update.

Released version 2.6.4 which should fix the issue for you. Let me know.

It worked! Thank you so much, you’re a lovely man ??

Awe, I’m blushing. Glad I could help!
