Hi,
When I checked my error log there are lot of database errors as showing in screen shot link ( https://i.paste.pics/4YSKS.png ). The reason I think might be because of few days ago I had noticed that wp-content folder of my sub-domain was not present in its directory but it was in another public_html directory (as shown in screen shot link https://i.paste.pics/4YSL9.png ). I have moved back this folder in its directory but my sites is not loading properly as it was working before this.
I will be very grateful if somebody can help me to fix these errors and can check if there are other errors in the site because someone said me your site is broken.
Regards,
Chetan
