Describe the bug

VM341:1 Uncaught SyntaxError: Unexpected token o in JSON at position 1 at JSON.parse (<anonymous>) at Object.success (bottom-65b1e2380.js:formatted:17208) at u (bottom-65b1e2380.js:formatted:1364) at Object.fireWith [as resolveWith] (bottom-65b1e2380.js:formatted:1415) at S (bottom-65b1e2380.js:formatted:3603) at XMLHttpRequest.<anonymous> (bottom-65b1e2380.js:formatted:3776)

the code involved is:

function paginateComments(page) { $.get(commentsListUrl, { page: page }, function(result) { const jsonResponse = JSON.parse(result); <--

I have faced this types of problem as well. i found a temporary work around for my problem. All i had to change is the "www" from the domain. As in "https://www.yourdomain.com/" to "https://yourdomain.com". See if this works for you. If not then you are probably facing something different than i was.

Hello @HartLarsson

I didn't manage to reproduce your issue with PS1.7.6.7 and ProductComments v4.1.0, see the attached screen record below:

https://drive.google.com/file/d/10w33uGHJZqm7tLk4q_ql3wvgCtXpcyc_/view

As you can see in the screen record above, I upgraded my ProductComments version from 4.1.0 to 4.2.0, and all approved comments are well displayed.
Could you please provide your ProductComments version (the previous one).

Please check and feedback.

Thanks!

Hello @HartLarsson

You probably have an override for list-comments.js file in your theme, could you check this?

[HartLarsson]

After some test i discovered that probably is a theme problem (warehouse).
I've already open a ticket with the developer that have a theme/module personalization not compatible with the new version, and is why that json error appear probably.

I will keep you informed on the evolution.

Hello @HartLarsson

hi @hibatallahAouadni
i've finally solved the problem was related to a theme module tpl not compatible with the new version of the official module.
I close the thread ;)
Ty for the support
