I will upload an update soon with this fix and some other minor tweaks. * [Graham](https://wordpress.org/support/users/aerin/) * (@aerin) * [9 years, 1 month ago](https://wordpress.org/support/topic/undefined-index-undefined-variable-errors/#post-9001158) * Hopefully the latest fixes all these (at least I don’t see them any more). * Thread Starter [hightechdad](https://wordpress.org/support/users/hightechdad/) * (@hightechdad) * [9 years, 1 month ago](https://wordpress.org/support/topic/undefined-index-undefined-variable-errors/#post-9002366) * Yep, not seeing these errors any more. Thank you! * [Larry Daniele](https://wordpress.org/support/users/larrydaniele/) * (@larrydaniele) * [8 years, 10 months ago](https://wordpress.org/support/topic/undefined-index-undefined-variable-errors/#post-9351475) * I’ve got QPP v5.5.1 running on WordPress 4.8 and PHP 5.6.30 and I’m still getting lots of errors in the log such as these: * > Today > 18:04:20 EDT Undefined variable: bg Type: PHP Notice Line: 1656 File:/ > home/rrcsadmin/public_html/wp-content/plugins/quick-paypal-payments/quick-paypal- > payments.php > Today > 18:07:43 EDT Undefined variable: header Type: PHP Notice Line: 1655 > File: /home/rrcsadmin/public_html/wp-content/plugins/quick-paypal-payments/ > quick-paypal-payments.php > Today > 18:07:46 EDT Undefined variable: submitfont Type: PHP Notice Line: 1636 > File: /home/rrcsadmin/public_html/wp-content/plugins/quick-paypal-payments/ > quick-paypal-payments.php > Today > 18:07:46 EDT Undefined variable: submitfont Type: PHP Notice Line: 1633 > File: /home/rrcsadmin/public_html/wp-content/plugins/quick-paypal-payments/ > quick-paypal-payments.php > Today > 18:07:46 EDT Undefined variable: font Type: PHP Notice Line: 1623 File:/ > home/rrcsadmin/public_html/wp-content/plugins/quick-paypal-payments/quick-paypal- > payments.php > Today > 18:07:46 EDT Undefined variable: inputfont Type: PHP Notice Line: 1621 > File: /home/rrcsadmin/public_html/wp-content/plugins/quick-paypal-payments/ > quick-paypal-payments.php * So it seems to still be a problem to me. I’d be glad to test or try anything reasonable to help debug this. * [Graham](https://wordpress.org/support/users/aerin/) * (@aerin) * [8 years, 10 months ago](https://wordpress.org/support/topic/undefined-index-undefined-variable-errors/#post-9354462) * Upgrade your php to V7. That will get things updated to the correct standard. * None of those messages stop anything working, it’s just PHP getting all narky because I call the variables before defining them. However, not sure why you are seeing them as they were all cleared at the last update. * I’ll do some investigation while you are upgrading to php7. * [Larry Daniele](https://wordpress.org/support/users/larrydaniele/) * (@larrydaniele) * [8 years, 10 months ago](https://wordpress.org/support/topic/undefined-index-undefined-variable-errors/#post-9354829) * Thanks for your suggestion. My client’s site is hosted on GoDaddy and sadly PHP 7 was not an option in the past. But I see that GoDaddy just announced support for PHP 7.0 and 7.1. I’ll give PHP 7.1 a whirl! * [k1rah](https://wordpress.org/support/users/k1rah/) * (@k1rah) * [8 years, 10 months ago](https://wordpress.org/support/topic/undefined-index-undefined-variable-errors/#post-9361685) * I am also seeing a bunch of these errors. I have debug set to ‘true’ so I can see them on screen. * Unfortunately using PHP 7 is not going to be an option for everyone. When I changed to PHP 7, I got a fatal error “unable to connect to database” from other plugins. * [Graham](https://wordpress.org/support/users/aerin/) * (@aerin) * [8 years, 10 months ago](https://wordpress.org/support/topic/undefined-index-undefined-variable-errors/#post-9361717) * They aren’t errors. They are just messages from PHP telling you that a variable hasn’t been defined before use. * I do try to catch them all but with over 2000 variables used in the plugin some slip through the net. * Set debug to false and you won’t see the messages. * PHP 5.X is no longer supported, you will at some point have to upgrade to PHP 7. Not doing so may put your site at risk.
