From today 3 April 2017 I have started getting errors like this:
currency, item name or number or quantity mismatch: IPN item_name (1+ADULT-START+IMMEDIATELY+for+w43799) does not match basket item_name (1 ADULT-START IMMEDIATELY for w43799) nor their trimmed sizes for IPN (1+ADULT-START+IMMEDIATELY+for+w43799) and basket (1 ADULT-START IMMEDIATELY for w43799)
For some reason "+" signs are being added where there are spaces in the IPN item_name. It does not happen for all payments and it is happening across different subscription plans. Some of my plans are in Japanese, but the "+" sign only is added between English words. For example:
currency, item name or number or quantity mismatch: IPN item_name (1年更新 大人1人 :レベル ブロンズ+for+w39146) does not match basket item_name (1年更新 大人1人 :レベル ブロンズ for w39146) nor their trimmed sizes for IPN (1年更新 大人1人 :レベル ブロンズ+for+w39146) and basket (1年更新 大人1人 :レベル ブロンズ for w39146)
I have not made any changes to any aspect of our system for many weeks.
Any idea why this might be happening and how I can fix it?
This looks like a bug on Paypal side. Please contact their helpdesk to ask them why they suddenly replace spaces by +'s in their POST forms. It happened already in the pat, and they fixed it quickly.
I have implemented a workaround for that Paypal bug (basically if the item_name check fails, re-try checking with an urldecoded version of it), tested it, and made a CBSubs new nightly build, available in our Downloads section.
I have also advised Payapl about their bug that probably affects many shopping carts.
