could resolve the problem by changing the file user-access-manager.php line 1126
<input type=”radio” id=”uam_download_type_fopen” name=”uam_download_type” value=”fopen” <?php if ($uamOptions[‘download_type’] == “fopen”) { echo ‘checked=”checked”‘; }?> />
I changed the echo
{echo”;}
to resolve this problem did the steps:
1 – between the configuration of All in One SEO Pack
2 – there will have the option Plugin Status: () enable () disable
3 – I saved the changes
4 – problem solved
