bsmither Posted November 23, 2019 Share Posted November 23, 2019 A CubeCart URL of the form, index.php?_g=getSomething, it is usually the case that there is something happening in the page on your browser working behind the scenes. In this case, getSomething is a request that CubeCart does not know what to do with. Unfortunately, the error does not mention what item of information CubeCart was supposed to get. As of CC628, the information CubeCart knows what to calculate and send back to the web browser are: ajax_cookie_consent: to log when the customer agreed to accept cookies ajax_price_format: respond with a properly formatted price with currency symbol, etc ajax_mail: respond with whether or not this email address is available to use ajaxadd: respond with new HTML to replace the existing Shopping Basket HTML code, having newly added an item remote: respond with the result of making a module perform some action - usually check the validity of a transaction in progress with the payment processor There is a hook to be able to use additional getSomething code snippets or plugins. So, if the getSomething was not one of these five (or serviced by a code snippet) processes, CubeCart complains about no callback method available. (The web browser is making a "call back" to CubeCart to get something.) If you can find the related URL that got logged in the web server's access logs, at the same time adjusted for timezone differences, you will learn what the getSomething was.

havenswift-hosting Posted November 25, 2019 Share Posted November 25, 2019 Hi Claudia I have made a small change to the code on that line in order to highlight what the rogue "getSomething" is and will let you know Ian Link to comment Share on other sites More sharing options...

Claudia M Posted November 25, 2019 Author Share Posted November 25, 2019 I don't know if the 2 are related but I can't see my store. It is just a white screen. Link to comment Share on other sites More sharing options...
Claudia M Posted November 25, 2019 Author Share Posted November 25, 2019 Hey Ian, Did you change my code on line 321 to } trigger_error('No useful GET['_g'] callback method defined. Got _g='.filter_var($_GET['_g'],FILTER_SANITIZE_STRING), E_USER_WARNING); httpredir('index.php'); } That is why I was getting the white screen. I changed it back to stock and now I can see my store. } trigger_error('No callback method defined.', E_USER_WARNING); httpredir('index.php'); } Me I have 123 of these system errors in admin Today, 11:16 [<strong>Exception</strong>] /home/claudias/public_html/classes/cubecart.class.php:321 - syntax error, unexpected '_g' (T_STRING), expecting ')' Link to comment Share on other sites More sharing options...
bsmither Posted November 25, 2019 Share Posted November 25, 2019 Well, the bold one is, no doubt, an experiment to show that CubeCart doesn't know what to do with getSomething. The other two, where Supreme Support referred to your site, is simply asking for the homepage. Ian meant to do this: trigger_error("No useful GET['_g'] callback method defined. Got _g=".filter_var($_GET['_g'],FILTER_SANITIZE_STRING), E_USER_WARNING); Needed to change some quote marks. Link to comment Share on other sites More sharing options...

Claudia M Posted November 25, 2019 Author Share Posted November 25, 2019 That's ok Ian. Thanks for helping me with this. Can I empty my error logs now? Link to comment Share on other sites More sharing options...
havenswift-hosting Posted November 25, 2019 Share Posted November 25, 2019 Yes you can - I have updated the class file with the correct code now (and checked your site worked !) so hopefully that will give us a clue as to what is going on Link to comment Share on other sites More sharing options...
bsmither Posted November 25, 2019 Share Posted November 25, 2019 My interest is why the code to deal with _g is happening. The web access log says it is just GET / (the default doc - homepage) with no querystring. So, something is adding a potentially unwanted querystring, or a plugin or code snippet is adding to the $_GET array during CubeCart's wake-up sequence.
