Highend options – not saving some changes

Highend Theme Options – not saving some changes.

wp_config.php is OK, lines are:
define(‘WP_MEMORY_LIMIT’,’128M’);
set_time_limit(120);

Strange behavior: it says saved successfully, but if you re-visit the page, the options are back to what they were before (i.e. not saved).

Only applies to selected options, changes not saving are:
Header Layout, Pre-Footer Callout, Footer Layout, maybe a few more.

I identified one of the plugins that creates this issue, it’s called WPML String Translation. Since you officially support WPML, can you please look into why this plugin creates a conflict?

I can provide a copy of the plugin if needed.

Thank you!

P.S. Also, it says “Saving failed” instead of “No changes made” in the options, which is a bit misleading.
