 When using the curl functionalities you need to enable the extension in your php.ini file on windows: extension=php_curl.dll on linux*: extension=php_curl.so It could happen, for example, on opencart with this error: Fatal error: Call to undefined function curl_init() in admin/controller/sale/order.php on line 84 -

Fatal error: main(): The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "PMA\libraries\ThemeManager" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in \libraries\common.inc.php on line 702 Fast solution - Just delete the cache in your browser :)

 iframe not positioned correctly in chrome or safari (webkit) with rtl (ex. arabic language) I got a problem with an iframe like this one <iframe src="page.html" width="360px" height="120px" marginwidth="0" marginheight="0" hspace="0" vspace="0" frameborder="0" scrolling="no"></iframe> I solved by just setting a fixed width from the CSS and chrome positioned the iframe as expected. I spent 1 hour on this stupid thing and I really don't like to fix such an old crap.
