Stop update to 2.6.4 before backup

https://downloads.www.ads-software.com/plugin/mqtranslate.2.6.3.zip

wordpress 3.9.1
with mqtranslate 2.6.4
site blanked under any theme

hope there is solution

We did not encounter this bug on any of our test site.

If you could provide some help, it will be greatly appreciated.
For example, you can update once more to mqTranslate 2.6.4 and add at the start of your main index.php file the following lines:

ini_set('display_errors', 1);
error_reporting(E_ALL);

It should display where the error occurs and we will be able to fix it very fast after that.

Thanks

BTW, thank you very much for this wonderful plugin.

once installed, more and nextpage shortcodes stop working

downgradded and everything works again

A new update will be available very soon to fix these issues.
Due to the blocking nature of these bugs, I hope to release it by the end of the day.

Resolved as of mqTranslate 2.6.5

a quick fix
you the best!

thank you ??
