WordPress database error: [Table ‘avis2933511657.wp_postmeta’ doesn’t exist]

Hello,

I really love this plugin. It has served my purpose for the last two years.

From last two months we have started seeing an error message on the career webpage.
The error message text is as mentioned below:

WordPress database error: [Table ‘avis2933511657.wp_postmeta’ doesn’t exist]
SELECT post_id FROM wp_yjch6vqa5f_postmeta WHERE meta_key = ‘_aol_ad_closing_date’ AND meta_value <= UNIX_TIMESTAMP() AND post_id NOT IN (SELECT post_id FROM wp_postmeta WHERE meta_key = ‘_aol_ad_close_type’ AND meta_value != ‘ad’)

I have done plenty of research to resolve this error but unable to do so. Will appreciate your help with this matter.
