I'm a teacher and have used multisite WP for two years now as a resource for completing assignments. This spring semester, I have the most students that I've had on my site (30). Prior to this semester I've a max of 26 with no problems. Unfortunately, I've had constant slow downs: either timing out, 500s, or the WP error establishing connection to database.
I use hostmonster as my host and have emailed them. They told me to install a cache plugin and activated it site-wide (WP Super Cache). This didn't really help, though.
Besides server-side issues, I'm wondering about two different possible problems:
1. Connection speed / firewall issue in my school district (which I'm waiting to hear back)
2. The location of this install on the grandchild level of the server: public_html (main domain for the server) -> add-on domain -> sub-directory -> student sites
Could #2 be my problem? The server is based off of my personal site/domain and any other additional. It views add-on domains as sub-directories (domain1.com/domain2), but parks it as it's own domain (domain2.com). Could all the sub-directories be the problem?
Is there anything I could be missing? Does this make sense? Help? Please and thank you.
