Slow queries

[patzo]

hi guys,

since our update, our website has been running very slow, so we disabled all the plugins and activated the twenty fifteen theme.

we checked through query mentor and notched we have a very slow query in the includes/template.php 613 file

the slow query is as follows;

SELECT DISTINCT meta_key
FROM wphq_postmeta
WHERE meta_key NOT BETWEEN '_'
AND '_z'
HAVING meta_key NOT LIKE '
_%'
ORDER BY meta_key
LIMIT 30

our site was running fine and we only updated the wordpress core and we had issues. your advice would be great.

query monitor results with no plugins.
