Hi,
I'm not sure when this error started as I've run a couple of updates to various plugins recently, but I just noticed it today as follows:
Missing argument 2 for PLL_Frontend_Filters::getarchives_where() in /home/xxx/public_html/wp-content/plugins/polylang/frontend/frontend-filters.php on line 159 and line 146
I believe there's a conflict with Polylang plugin somewhere.
Could you please help?
Thanks,
Eunike
