WordPress Speed Up Service | WordPress Website Maintenance Packages Left side tool bar icons., by scottkr24 On the far left side of WP Admin we have those icons. The last one at the bottom is to expand or collapse the vertical bar. A client of mine who maintains their own site is having an issue. The expand/collapse icon isn’t working. You click on it, nothing happens. Its currently in the collapsed mode. Need to get it back to the expand mode. Any idea of what’s going on? Left side tool bar icons.
