Job ID: 31893677

Budget: $10 – $30 USD

Hello,

Every time I make changes in administrator, website will go down, there may be missing important files due to an update or so.
See attachments.

I was making some changes, extension updates and it stopped working. https://www.accessscanning.com/
I contact my website host and they did not find the issue.
