I have the same problem. php.ini is fine. Rebooted multiple times. Database config is set to 524288000 bytes (500MB). Etc.
I have poured through the code yet I cannot figure out what's wrong. My error is "File too big. Max file size 500MB" yet I cannot upload any file more than like 1MB.
I have somewhat narrowed down the error. I don't think PHP is the issue (I could be wrong though) because the errors in UploadController.php don't trigger. The actual error that's thrown lies in resources>views>frontend>global>includes>uploadbox.blade.php on line 154
$exceedTheAllowedSizeError = str_replace('{maxFileSize}', subscription()->formates->file_size, lang('File too big. Max file size: {maxFileSize}', 'upload zone'));
Anybody have a solution?
