I agree with you, you are 100% right, I noticed when i use my email that also hosted by the same host, all works perfect, then when i change the email to my client email which is gmail it did not work, then I created another email ** This email address is being protected from spambots. You need JavaScript enabled to view it. which is support by hikashop it also the error came back, then i called the hosting company and discus with them the issue let them also try the website, so the engineer mention there is another email some where saved in hikashop which is This email address is being protected from spambots. You need JavaScript enabled to view it. , and I do remember that i created this email long time then i have removed it, so making the long story short, i recreated this email and put it in the hikashop email and all works fine, again thank you, I will post a better details on monday, just last information usually i develop the website first in something like dev.myclientdomain.com then when al done i use akeeba backup to move it to myclientdomain.com, i should i delete the dev folder and the database i think that also cause an error, thanks
