Hi,
It appears that our error log kept growing and the server went down. We then removed old backup data, and deleted the /var/www/vhosts/petelements.hk/PE/system/logs/error.txt file and recreate a new one. We tried rebooting the server but no use. We noted that the admin login screen can be shown, but after typing in username and password, the browser went to an url like http://www.petelements.hk/admin/index.p ... 4ec00ba550 but the screen is blank. I know the opencart we use has a server cache installed. There are many files in the /var/lib/php/session folder. What do you think we can do to recover the website? Any tips appreciated, thank you.

Well, in a professional Setup, there should be no Error Logs. And you did
not check your Installation, and clear out any Cache and Error Sections for
a long time, as it looks. But first DISABLE this PageCache Function, and clean
out the Page-Cache File Directory, since this function does not work, exept
for producing endless Error Entries.

We know the Cache module can cause the whole website not displaying properly. But when we dig into the log messages, we noted that there is a oc_customer_online table that is reported to be corrupt. We tried to export the table, delete it, and re import it - only to see error saying that a key already exists.
If the corrupt DB table is causing the website to fail presenting, what can we do? The more problems the site has now, the more we feel wanting to hire an opencart expert here to rebuild the online shop. What kind of spending is required for a job like this?
In the past when I took over the site after previous staff left, I noted that the cache module can cause the website not displaying or malfunction. However there seems a bug so that in the admin screen i cannot turn off this feature. So it is a pain in the ass for me.

Sure, you can turn off the Page Cache Extension, at least, if you have this
Extension installed. And you can remove it as well, by comparing the Shop
Site Files with the Content of the downloaded Extension, and remove, what
belongs to the Page Cache Extension. (AFTER you switched it off in the Admin!)

It seems that your session folder is full.
So session files can not be writen anymore, wich in term is causing your admin login problems.
Session folder is located /var/lib/php/session

Clean out that folder.
