3 small dedicated server projects - Project for EverytingIT

Project 1: We need to enable "mb-string" on the server If you check on this page: [login to view URL] lish-by-ph one. com/teachers/ - click on the small speaker icons under each pictures. Since we transferred the English-by-phone website to the new dedicated server, the audio player stopped working. Note that we are really afraid to repeat the same issue we just had; the last time we tried to enable "mb-string", it affected the setup to [login to view URL] and we lost the possibility to send emails using php. Project 2: When we send email (from our php application) to @[login to view URL], @[login to view URL] and @[login to view URL], none of these clients receive the email. It used to work properly a month ago but stopped about 2 weeks ago. Every other email accounts work perfectly. Project 3: We receive this emails almost on a daily basis: Subject: [cPanel smartcheck] Possible Hard Drive Failure Soon S.M.A.R.T Errors on /dev/sda From Command: /usr/sbin/smartctl -q errorsonly -H -l selftest -l error /dev/sda Please note the following marginal Attributes: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 190 Airflow_Temperature_Cel 0x0022 055 035 045 Old_age Always In_the_past 45 ----END /dev/sda--
